to pop up its description (if any).
An instance of the OUT_MATRIX function block type
provides a tabular user interface element for output of MATRIX
variables.
The table is not initially displayed upon the occurrence of an INIT
event, since its size and contents are not yet defined.
Upon the occurrence of a REQ event, the size and
contents of the displayed table are automatically adjusted as
necessary to accommodate the new value of the IN matrix.
See the MATRIX_DEMO,
M_OPS_DEMO
and CODEC_TEST2
system configurations for examples of the use of instances of this
class.
