@David Craven: what is selectcolumn ?
Why not use very simple and efficient indexing?

I can’t find a ‘selectcolumn’ function in the online documentation or the File Exchange.
If ‘M’ is your matrix, either:
Out = M(:,[1 10:10:end]);
or:
Out = M(:,1:10:end);
depending on how you define ‘every 10th column’.
