How do I have a loop for different data intervals.
显示 更早的评论
I have a (m by n) matrix, for example:
A=rand(m,n)
First, I need the operations for the following submatrix (with different lengths).
A1=A(1:10,:)
T1=A1’*A1
A2=A(11:22,:)
T2=A2’*A2
A3=A(23:40,:)
T3=A3’*A3
and more ….
That is, I need different data interval for computations.
How can I do it by using a loop command?
Thank you very much.

A=rand(50,10);
idx = [1 10; 11 22; 23 40];
for i=1:size(idx,1)
Anow = A(idx(i,1):idx(i,2), :);
T = Anow'*Anow;
end
