Description

Addition.

For numeric operands addition as its usual meaning. If one of the operands is a matrix and the other one a scalar the scalar is added to each matrix entries. If one of the operands is an empty matrix the other operand is returned (this default behavior can be modified by the function mtlb_mode).

For character strings + means concatenation.

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

Examples

[1,2]+1
[]+2
s=`poly`_(0,"s");
s+2
1/s+2
"con"+"cat"+"enate"
