Triangle pyramid of numbers (0-9), but to return as output var.

function [res]=WORKI_05(number)%NUMBER IS UNSIGNED INTEGER(TRIANGLE HEIGHT),RES IS MY OUTPUT.
value=int16(0);%MY TRIANGLE HAS VALUES FROM 0-9.
for i = 1 : number
    for z=1:number-i
        fprintf(' ');
    end
    for y=1:2*i-1
        if value==10 %0-9 LOOP
            value=0;
        end
        fprintf('%d',value);
        value=value+1;
    end
    for j=1:number-i
        fprintf(' ');
    end
    fprintf('\n') ;
end
end

But I need to use the function return value 'res', so my question is how to work with fprintf to save directly in var and then to return it.

See below for an example of how to do this with sprintf:

function [res]=WORKI_05(number)%NUMBER IS UNSIGNED INTEGER(TRIANGLE HEIGHT),RES IS MY OUTPUT.
res = repmat(' ',number,2*number+1);
value=int16(0);%MY TRIANGLE HAS VALUES FROM 0-9.
for i = 1 : number
%     for z=1:number-i
%         fprintf(' ');
%     end
    for y=1:2*i-1
        if value==10 %0-9 LOOP
            value=0;
        end
%         fprintf('%d',value);
        res(i,number-i+y) = sprintf('%d',value);
        value=value+1;
    end
%     for j=1:number-i
%         fprintf(' ');
%     end
%     fprintf('\n') ;
end
end

See here for an example of how to do this without sprintf.

@Benjamin Thank you!

works very fine now.

You would use sprintf() instead of fprintf().

res = sprintf(..................)

@Image Analyst that's the output after I used sprintf() instead of fprintf()

Then why did you accept Benjamin's answer? He told you to use sprintf() also:

res(i,number-i+y) = sprintf('%d',value);

Are you saying that sprintf() doesn't work? Obviously you were supposed to replace the dots in my code with whatever you had in fprintf(), so I'm assuming you did that.

However you tell me sprintf() does not work and you tell him it does work. Seems like a contradiction to me. OK, whatever, as long as you got it figured out.
