Some problem in taking values from particular text file

1 view (last 30 days)
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?

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

Because Azzi wrote code for exactly what you said, but you are not saying what you want. Please describe what you want accurately next time.

Is this what you intended?
function Z = cssm
A = randi( 12, [965,365] );
Z=[];
n=1;
N_end = 964;
for i=1:4:364
Z(n:n+N_end,1)=A(:,i+2);
Z(n:n+N_end,2)=A(:,i+3);
Z(n:n+N_end,3)=A(:,i);
n=n+N_end + 1;
end
end
Anyhow, it returns a result.
