Description
Subtraction
For numeric operands subtraction as its usual meaning. If one of
the operands is a matrix and the other one a scalar then the operation is
performed element-wise. For X - Y, if Y == [] or Y == [] then [] is returned;
Subtraction may also be defined for other data types through "soft-coded" operations (see overloading).
