What is the best way to define an output vector in this case?

Suppose

• I run 1000 loops
• For each loop, I generate 10 dimensional vector as an output
• I want to create a 1000*10 dimemsional vector that records outputs from 1000 loops
• Then I want to create a histogram of the output vector, etc

What would be the best way to define an output vector in this case?

I assume you mean a 10-element vector.

for k=1:1000
    yourVector=;%computation to compute your vector
    yourMatrix(k,:)=yourVector;%this will by 1000x10 matrix containing each loop's vector
end
histogram(yourMatrix);

Thank you. But how about calculating mean, standard deviation? It seems that I cannot just do mean(yourmatrix) as "If A is a matrix, then mean(A) returns a row vector containing the mean of each column." Shall I just do mean(mean(yourmatrix))?

As another extention, suppose each iteration now gives a 10*10 matrix (not just a 10 dimensional vector). Then how can one define an output vector in such a situation?

for k=1:1000
    yourMatrix;
    newMatrix(:,:,k)=yourMatrix;%3D matrix
end
