MATLAB: Some problem in taking values from particular text file

debug

I have a matrix A 965*365 want to make from this matrix a matrix Z such that it is having only three rows such that in 1st row value of A(:,1), A(:,4), A(:,7) and so on and in second row value of A(:,2), A(:,5) and so on and in third row value of A(:,3), A(:,6) and so on
    Z=[];n=1;
    for i=1:4:3864
    Z(n:n+965,1)=A(:,i+2);
    Z(n:n+965,2)=A(:,i+3);
    Z(n:n+965,3)=A(:,i);
    n=n+965;
    end
Subscripted assignment dimension mismatch.
Plz tell me how can I solve it?

Best Answer

A1=A(:,1:3:end);
A2=A(:,2:3:end);
A3=A(:,3:3:end);
out=[A1(:) A2(:) A3(:)]'
