How to append vector in a for loop
显示 更早的评论
Hi there,
I have a for loop that creates an 10x10 vector in each iteration. My question is how can I append each 10x10 vector underneath each other after each iteration. So that the final vector is 30x10.
Thank you for your time
for i=1:3
% Do stuff
%result is 10x10 vector A
end

B = [];
for ii=1:3
A = randi(10,10); % this is the code to create the 10x10
B = [B ; A];
end

How to do it if I want to do it a million times? Is there a collect way to preallocate?
