2.12 Matrix Operators

The fundamental unit in the SAS/IML language is the matrix. This section describes how to perform arithmetic operations that involve scalars, vectors, and matrices.

2.12.1 Elementwise Operators

The elementwise operators in the SAS/IML language consist of one unary operator and several binary operators. The unary operator is the negation operator (-), which is equivalent to multiplication by -1. The elementwise binary operators are the addition operator (+), the subtraction operator (-), the elementwise multiplication operator (#), the division operator (/), and the power or exponentiation operator (##).
