is it possible in matlab to change coluns:
A=[a1 a2 a3 a4.......a2250],a1...a2250 are arrays oth size(30*1).
i want to get this matrix B=[a1 a75 a150.... a2 a76....a3 a77..... ]. that means i have a step of 74
i wish you could help thank you

B = reshape(permute(reshape(A,size(A,1),75,),[1 3 2]),size(A,1),);
s = size(A,2); B = A(:,bsxfun(@plus,1:75:s,(0:(s/75-1))')');
B = A(:,reshepe(1:size(A,2),75,)');
