save all columns into a new variable in a loop

I have the following setup. Every time k changes i get new values of T.

T is of size 1x1000, so i want to end the end have a 3x1000 matrix.

for k =1:3
T = myfunc( X, r)  
end

Use indexing:

T = nan(3,1000); % preallocate!
for k = 1:3
    T(k,:) = myfunc(X,r);  
end

Funny thing i just did it. haha thanks though. I was doing T(:,k) and i just switched it and it worked. I really need to master indexing of matrices/vectors

"I really need to master indexing of matrices/vectors"

Yes. Efficient indexing of arrays, matrices, and vectors is really one of MATLAB's key strengths.
