cumsum broken in two to hide recursion args and avoid repetitive arg validations.

back_substitute changed to avoid repetitive arg validations in the recursion.

minor change in deriv2 and deriv3 to avoid an unecessary call to is_matrix.

change in is_matrix for better performance

any() and all() broken in two to avoid repetitive arg validation in the recursion and to hide recursion args.
