operators
Subtracts two parameters.
The - operator consumes two parameters from the top of the stack and pushes back the result of subtracting the second one from the first one.
-
If both parameters are numbers, the result is the subtraction of both numbers.
-
If both parameters are vectors, the - operator subtracts each element of vectors which are on the same index. Vectors must be the same size.
-
If both parameters are matrices, the - operator subtracts each element of matrices which are on the same index. Matrices must be the same size.
