Hello Everyone, I am new in MATLAB and I want to get result of this code(MATLAB2021a), its run correctly but doesn't show the result. Anyone can help me?? thanks in advance

c=[ ];
global d;
c(1,d)= ran(10,21);
function x = ran(min,max)
x= fix ((max-min).*rand(1,1) + min)+1;
end

It should give me number but doesn't show any numbers.

Many Thanks for your help

[KALYAN ACHARJYA]

c=[ ];
c= ran(10,210)

Please do google - MATLAB Onramp

[ARAM KHURSHEED]

@KALYAN ACHARJYA Thank you so much, its work like you wrote,but i need it to give me result as c(1,d)=ran(10,21); becuase its a part of my program. could you tell me why NewNetwork doesn't get the result??

OP's comments moved here.

i want to get this table

the attachment code is to create this table, the result should be save in NewNetwok but this not occure this is my problem .

Dear @Cris LaPierre,

Did you fix the issus?

Answer 1

[Cris LaPierre]

Here is perhaps some starter code for you on how to create a MATLAB table.

rowNms = ["WIFI";"WIMAX";"UMTS";"LTE"];
varNms = ["CostperByte","Security","DataRate","PacketDelay","PacketJitter","PacketLoss"];

newNetwork = array2table(zeros(4,6), 'VariableNames', varNms);
newNetwork.Properties.RowNames = rowNms;

for r=1:height(newNetwork)
    for c = 1:width(newNetwork)
        newNetwork{r,c}=ran(randi(100,1),randi(100,1));
    end
end
newNetwork

newNetwork = 4×6 table
             CostperByte    Security    DataRate    PacketDelay    PacketJitter    PacketLoss
             ___________    ________    ________    ___________    ____________    __________

    WIFI         21            47          46           70              61             39    
    WIMAX        17            57          52           58              80             55    
    UMTS         65            57          36           51              62             29    
    LTE          30            29          32           72              19             71    

function x = ran(min,max)
x= fix ((max-min).*rand(1,1) + min)+1;
end

[ARAM KHURSHEED]

Dear @Cris LaPierre,

Thank you so much, hope all the best to you

Best Regards

[ARAM KHURSHEED]

Dear @Cris LaPierre,

sorry for annoying, but could give me some more explain about the code, because each Network("WIFI";"WIMAX";"UMTS";"LTE") has different random range of Attribute("CostperByte","Security","DataRate","PacketDelay","PacketJitter","PacketLoss") so, how can i do that?

Could you applay your code on for example on the one network?

Best Regards

[Cris LaPierre]

Why don't you make an attempt, and then I can answer specific questions you have about doing it.

[ARAM KHURSHEED]

Dear @Cris LaPierre,

I am doing but i can not get result.

for example, i would like to genereat values (CostperByte","Security","DataRate","PacketDelay","PacketJitter","PacketLoss) for network WIFI

assume this code

switch NetworksList(i)
    case 'WIFI'
        NewNetwork(1,CostperByte)=5 ;
        if mod(WIFIToString,2) == 1
            NewNetwork(1,CostperByte)=10 ;         
        end
        NewNetwork(1,Security)= 50;
        NewNetwork(1,DataRate)= ran(1,11);
        NewNetwork(1,PacketDelay)= ran(100,150);
        NewNetwork(1,PacketJitter)= ran(10,20);
        NewNetwork(1,PacketLoss)= ran(20,80);
        WIFIToString=WIFIToString+1; 

i tried to applay your code on the above code but i coudn't to do that i have wrote mentioned code after the two for loop but doesn't give me resault, like:

        global UMTS;
        global LTE;
        global WIFI;
        global WIMAX;
        global FiveG;
        global CostperByte;
        global Security;
        global DataRate;
        global PacketDelay;
        global PacketJitter;
        global PacketLoss;
        WIFIToString=1;
        UMTSToString=1;
        rowNms = ["WIFI";"WIMAX";"UMTS";"LTE"];
        newNetwork.Properties.RowNames = rowNms;
        for r=1:height(newNetwork)
            for c = 1:width(newNetwork)
                switch rowNms(r)   
                    case 'WIFI'
                        newNetwork(r,c)=10 ; 
                        newNetwork(r,c)= 50;
                        newNetwork(r,c)= ran(1,11);
                        newNetwork(r,c)= ran(100,150);
                        newNetwork(r,c)= ran(10,20);
                        newNetwork(r,c)= ran(20,80);
                        WIFIToString=WIFIToString+1;

this dosen't work

Best Regards

[Cris LaPierre]

Why are you declaring globals? Is there another script that calls this one?

[ARAM KHURSHEED]

Dear @Cris LaPierre,

No, for now there is no more script, it my mistake i entegrated your code with my code, i removed the global but still no result.

Best Regards

[Cris LaPierre]

Have you gone through MATLAB Onramp yet?

[ARAM KHURSHEED]

Yes, Yesterday i have done some tasks

[Cris LaPierre]

Here's an example of how I would create the first row. Since you have to code every cell already, I don't find any value in encasing everying in a switch statement.

Be careful with variable names. As you learned in MATLAB Onramp, captialization matters. NewNetwork is not the same variable as newNetwork.

rowNms = ["WIFI";"WIMAX";"UMTS";"LTE"];
varNms = ["CostperByte","Security","DataRate","PacketDelay","PacketJitter","PacketLoss"];

newNetwork = array2table(zeros(4,6), 'VariableNames', varNms);
newNetwork.Properties.RowNames = rowNms;

% WIFI
newNetwork{'WIFI','CostperByte'}=5;
newNetwork{'WIFI','Security'}= 50;
newNetwork{'WIFI','DataRate'}= ran(1,11);
newNetwork{'WIFI','PacketDelay'}= ran(100,150);
newNetwork{'WIFI','PacketJitter'}= ran(10,20);
newNetwork{'WIFI','PacketLoss'}= ran(20,80);

newNetwork

newNetwork = 4×6 table
             CostperByte    Security    DataRate    PacketDelay    PacketJitter    PacketLoss
             ___________    ________    ________    ___________    ____________    __________

    WIFI          5            50          4            108             15             67    
    WIMAX         0             0          0              0              0              0    
    UMTS          0             0          0              0              0              0    
    LTE           0             0          0              0              0              0    

function x = ran(min,max)
x= fix ((max-min).*rand(1,1) + min)+1;
end

[ARAM KHURSHEED]

@Cris LaPierre,

So, you removed the for loops and switch statement.

Exactly, There is no values when encasing in switch statement, i have tried this idea but i wanted to get the result by switch statement and using for loops, maybe this needs more effort and experince and i am new in this field thats why i couldn't.

my reason to use switch and loop because i want do that for example for 50 times(50 tables) with keeping the values for all of them.

in your opinion i have export the values as .xls(excel file) file to keep the older values or there is another ways?

about captialization matters, Yes you are right, its called sensetive case i know that i corrected it later.

@Cris LaPierre Thank you so much, please accept my apologies, I bothered you and I am grateful to you

Keep shining

Best Regards

[Cris LaPierre]

You will need to find some solution for saving the result of each loop, otherwise each loop will overwrite the result of the previous loop, so at the end you will just have one table - the result of the last loop. If you need the table in MATLAB, perhaps consider using a structure.

[ARAM KHURSHEED]

How can i convert the table to Matrix because i want to deal with the values of this table?

I have script which deal with the values of the table.

i have tried these but not useful

newNetwork = table(magic(6));

and also

newNetwork={ : :}

[Cris LaPierre]

I don't understand what you are trying to do with the code you shared. They appear to be unrelated to what you are asking to do.

You don't need to convert it to a table. It is all about how you access the data. See this page:

https://www.mathworks.com/help/matlab/matlab_prog/access-data-in-a-table.html

[ARAM KHURSHEED]

Dear @Cris LaPierre,

Thank you so much

i have got it,

i have used the code below and its work

a=table2array(newNetwork);

Best Regards

[Cris LaPierre]

You lose all your row and column names by converting it to a matrix.

[ARAM KHURSHEED]

Exactly, I have to do that, I have no choice, I want to deal withe values inside the table, I will need only the network names (row names) in the end and at that time I have to think about that.

I am doing network ranking.

So, in the last i will need name of network but whole program is not ready, i am doing it partly(script by script).

Best Regards,
