How can I sort the output of a function into columns of three

Hi all, I'm a beginner so apologies if this is an obvious question but I've looked through a few tutorials and help guides and can't find anything that directly answer my question.

I have an input M with 3x295. When plotted it produces a nice cyclical graph but it's a bit noisy which I wish to reduce to be able to automatically find the minima/maxima.

When I use smooth(M) I end up with an output 885x1, could you please explain how I can get this into the same 3x295 format as M. Is there a general method I can use in all my future matlab code to make sure the output is the same in structure to the input?

Thanks for your help.

Try this:

Ms = (1:885)';

M = reshape(Ms, [], 3)';

Mv = M(:,1:10);

Ms is your smoothed M matrix (as a vector output from smooth), M is the reshaped version, and Mv lets you view the first few columns to be sure it’s what you want.

Perfct Star Strider that's exactly what I was after, thanks very much.
