10.6  Select Options

Certain options within MX, for example matrix comparison or matrix manipulation (10.8), operate either on the whole matrix or, optionally, on certain “selected” cells.  The select facility defines those cells.

Selection is based on:

♦      “Location”, e.g. select rows 1 to 5 and/or

♦      “Value”, e.g. select only those cells whose value is greater than 10.
