What's New in SAS/IML 9.2

Vector-Matrix Operations

SAS/IML elementwise operations now permit you to specify conforming vector-matrix operations. For example, if v is a 1 by n row vector, and s is an m by n matrix, then the expression v+s evaluates to the addition of v to each row of s. This change was introduced to reduce the need for explicit loops and increase the efficiency of this type of calculation. See the Language Reference chapter for full details of this change.
