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.
