GRID command

Syntax: | `GRID x y z m GRID\PATTERN x y z m GRID\INDICES x y z m`
Qualifiers: | `\INTERPOLATE, \PATTERN, \MESSAGES, \INDICES, \SIZE, \XYOUT, \BOUNDS, \CHECKDUP`
Defaults: | `\INTERPOLATE, \MESSAGES, \-SIZE, \-XYOUT, \-BOUNDS, \-CHECKDUP`

This command creates a regular matrix from scattered data points. The vectors `x`, `y` and `z` are assumed to represent scattered points, where `z` is the data value at location `(x,y)`. By default, a square matrix, `m`, is interpolated, with row and column dimensions equal to `5*sqrt(min(len(x),len(y),len(z)))`.

MESSAGES

If the `\-MESSAGES` qualifier is used, no informational messages will be displayed.

CHECKDUP

By default, duplicate `(x,y)` locations are not checked for before the matrix is made. If you want duplicate points to be ignored, use the `\CHECKDUP` qualifier.
