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==[] then X is returned; if X==[] then -Y is returned.

Subtraction may also be defined for other data types through “soft- coded” operations (see overloading).

Examples

[1,2]-1
[]-2

%s-2
1/%s-2
