How to print multiple Values using sprintf In matlab

Hello Everyone, I hope you are doing well.

I have the following dataset which consists of following values . I am trying to print the values using sprintf. But extra values are printing

The sprintf output should be like

'DS Levels: 2

DS Value: [333 343]

DS Length: [ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 19 23]

Maximum Value of DS:343'

Minimum Value of DS:333'

but i am getting the ouput like the following

'DS Levels: 2

DS Value: [333 343 1]

DS Length: [2 3 4 ]

Maximum Value of DS:5

Minimum Value of DS:6

DS Levels: 7

DS Value: [8 9 10]

DS Length: [11 12 13 ]

Maximum Value of DS:14

Minimum Value of DS:15

DS Levels: 16

DS Value: [17 19 23]

DS Length: [343 333 '

z=1;
pred1 = sprintf('DS Levels: %d\n DS Value: [%d %d %d]\n DS Length: [%d %d %d ]\n  Maximum Value of DS:%d\n Minimum Value of DS:%d\n ',CombineOutput(z).PRFStructure.Levels,unique(CombineOutput(z).PRFStructure.DSPRFValue),unique(CombineOutput(z).PRFStructure.DSlength),CombineOutput(z).PRFStructure.DSmaximum,CombineOutput(z).PRFStructure.DSminimum);
pred1

%% Its print the values the like following

% % % %  'DS Levels: 2
%       DS Value: [333 343 1]
%       DS Length: [2 3 4 ]
%        Maximum Value of DS:5
%       Minimum Value of DS:6
%       DS Levels: 7
%       DS Value: [8 9 10]
%       DS Length: [11 12 13 ]
%        Maximum Value of DS:14
%       Minimum Value of DS:15
%       DS Levels: 16
%       DS Value: [17 19 23]
%       DS Length: [343 333 '

Rather than hard-coding a fixed number of values to print, I recommend writing more robust code using STRING &JOIN or COMPOSE or SPRINTF to first create text of any number of values, then provide those to SPRINTF. For example:

S = load('matlab.mat');
T = S.CombineOutput.PRFStructure

T = 1×5 table
    DSPRFValue      DSlength      Levels    DSmaximum    DSminimum
    ___________    ___________    ______    _________    _________

    1×85 double    1×85 double      2          343          333   

Z = sprintf('DS Levels: %d\nDS Value: [%s]\nDS Length: [%s]\nMaximum Value of DS:%d\nMinimum Value of DS:%d',...
    T.Levels, join(string(T.DSPRFValue),' '), join(string(T.DSlength),' '), T.DSmaximum, T.DSminimum)

Z = 
    'DS Levels: 2
     DS Value: [333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333 343 333]
     DS Length: [17 16 16 17 17 16 16 17 17 16 16 17 11 12 17 16 14 17 6 14 16 16 17 4 2 3 6 12 17 8 4 3 4 6 17 13 8 1 1 10 3 2 17 14 7 14 19 14 6 15 16 17 17 6 3 9 4 2 17 7 3 5 4 1 17 10 8 5 17 14 10 12 17 16 16 17 17 10 23 16 16 17 17 16 14]
     Maximum Value of DS:343
     Minimum Value of DS:333'

If the text is ultimately going to be displayed in the command window or printed to a file, then skip SPRINTF and just go directly to FPRINTF:

fprintf('DS Levels: %d\nDS Value: [%d', T.Levels, T.DSPRFValue(1));
fprintf(' %d', T.DSPRFValue(2:end));
fprintf(']\nDS Length: [%d',T.DSlength(1));
fprintf(' %d', T.DSlength(2:end));
fprintf(']\nMaximum Value of DS:%d\nMinimum Value of DS:%d', T.DSmaximum, T.DSminimum)

That would probably be the most efficient approach.

@Stephen23 I have the following data in which I have StagPRFValue is cell array when i run the following code it gives error

Cell array input must be a cell array of character vectors.

Can you please modified it

T = CombineOutput.PRFStructure;
pred2= sprintf('Stagger Levels: %d\nStagger PRI Values: [%s]\Maximum Value of Stagger:%d\nMinimum Value of Stagger:%d',...
T.StagLevels, join(string(unique(T.StagPRFValue)),' '), T.StaggMaximumValue, T.StaggMinimumValue); 

[Stephen23]

"Can you please modified it"

You can use indexing to access cell array content:

S = load('newone.mat');
T = S.CombineOutput.PRFStructure

T = 1×4 table
    StagLevels    StagPRFValue    StaggMinimumValue    StaggMaximumValue
    __________    ____________    _________________    _________________

        9         {9×1 double}          2838                 2784       

%                         vvv        very basic cell array indexing
join(string(T.StagPRFValue{1}),' ')

ans = "2784 2787 2789 2793 2801 2802 2823 2824 2838"

@Stephen23 Thanks

This is due to the amount %d you have used. Only use 2 of them for DS Value and 19 for DS Length

update added a 'print string' which updates the amount of %d's automatically based on the struct

load(websave('myFile', "https://nl.mathworks.com/matlabcentral/answers/uploaded_files/1112565/matlab.mat"))

z = 1;

% create the print string
PrintStr = join(["DS Levels: ",repmat("%d ",1,numel(CombineOutput(z).PRFStructure.Levels)),"\n"...
			     "DS Value: ", repmat("%d ",1,numel(unique(CombineOutput(z).PRFStructure.DSPRFValue))),"\n"...
			     "DS Length: ",repmat("%d ",1,numel(unique(CombineOutput(z).PRFStructure.DSlength))),"\n"...
			     "Maximum Value of DS: ",repmat("%d ",1,numel(CombineOutput(z).PRFStructure.DSmaximum)),"\n"...
			     "Minimum Value of DS: ",repmat("%d ",1,numel(CombineOutput(z).PRFStructure.DSminimum)),"\n"]);

% print the text
pred1 = sprintf(PrintStr,CombineOutput(z).PRFStructure.Levels,unique(CombineOutput(z).PRFStructure.DSPRFValue),unique(CombineOutput(z).PRFStructure.DSlength),CombineOutput(z).PRFStructure.DSmaximum,CombineOutput(z).PRFStructure.DSminimum);

pred1

pred1 = 
    "DS Levels:  2  
      DS Value:  333  343  
      DS Length:  1  2  3  4  5  6  7  8  9  10  11  12  13  14  15  16  17  19  23  
      Maximum Value of DS:  343  
      Minimum Value of DS:  333  
     "

@Karim But it need to be uniform sometime i get DS Levels: 3 sometimes its DS Levels: 4

and DSValue also change with Respect to Levels.

[Karim]

I updated the answer so that the amount of %d's is determined automatically
