How to use output numbers as a vector.

The code I'm working on does what it's supposed to, however, I technically want it to output the values as a vector b instead of a message with the numbers.

The goal of this function is to input a vector and have the program sort them from smallest to largest, but without using the sort function.

The code I'm using is

clear variable
clc
a=input('Please input a vector of integers');
c=length(a);
for d = unique(a(:))
    b=(sprintf('%d',d));
end
clc
sprintf('b= ')
disp(b)

right now the answer I'm getting is:

ans =

    'b= '

2469

this is based upon the vector [9 4 6 2]

What I want to see output is:

b =

     2     4     6     9

this output was copied from my teachers p code and is technically what my output should look like.

Yes this is homework.

You're overwriting b every iteration. You also don't need the loop, as sprintf can handle array inputs just fine.

Also, this assignment (or your interpretation) seems a bit strange. Why would you be required to convert the numbers to characters as well? The output looks as if this is the source:

a=[9 4 6 2];
b=sort(a)

b = 1×4

2 4 6 9

Also, you're not using c, and you should check if the implicit call to sort inside of unique is allowed.

I'm new to this, and in all honesty I'm really not that great with it. I essentially am required to sort the vector without using sort. Your probably right that I can't use unique as well. My teacher just has me use google to learn syntax and I end up with weird ways of getting things done because I'm just trying to adapt what I can find thats similar. The assignment doesn't require that I change to characters.

I'm just trying to start over from the beginning for the time being.

There are may sorting algorithms you could implement. One of the easiest to implement (and one of the slowest) is called bubble sort. If you Google 'bubble sort Matlab' you will find several implementations. Otherwise I would suggest reading some Wikipedia pages and trying to implement it yourself.

Thank you, that worked for me.

hello

see bleow :

clear variable
clc
a=input('Please input a vector of integers : ');
c=length(a);
for d = unique(a(:))
    b=(sprintf('%d ',d)); % add a blank after "%d"
end
clc
sprintf('b = %s', b)

[Rik]

This code only works as intended because d is a column vector, all elements of a are integers, and there are no duplicate values.
