Hi, I have a matrix xx which is a 6x20 matrix, and I want to flip only the even rows. Im trying this but is doesn't work:
f=size(xx);
f=f(1);
f=0:1:f;
f=f';
for s=f+2
xx(f,:)=fliplr(xx(f,:));
end
I will appreciate any advice. Martha

A(2:2:end,:)=fliplr(A(2:2:end,:))

No need for a loop. Just do this:
xx(2:2:end,:) = fliplr(xx(2:2:end,:));

hello, how to rotate certain elements in different rows in a matrix? for example a=[1 2 3 8; 4 5 6 4; 7 8 9 3] suppose i want all elements in second and third column to be rotated row wise. output should be a=[1 5 6 8; 4 8 9 4; 7 2 3 3]
