I have a given matrix and I would like to delete every nth row. (Is there any particularity I have to keep in mind given that my matrix will generally not be a multiple of n?)

If your matrix is A, then
A(n:n:end,:) = [];
will delete every nth row. Your matrix row count does not need to be evenly divisible by n.
