SAMPLEXYT(DAT_TO_SAMPLE,XPTS,YPTS,TPTS) Returns data sampled at a set of (X,Y,T) points, using linear interpolation.
SAMPLEXYT_NRST(DAT_TO_SAMPLE,XPTS,YPTS,TPTS) Returns data sampled at a set of (X,Y,T) points, using nearest grid intersection
Arguments: |
DAT_TO_SAMPLE |
Data to sample |
XPTS |
X values of sample points |
|
YPTS |
Y values of sample points |
|
TPTS |
T values of sample points |
|
Result Axes: |
X |
ABSTRACT; length same as XPTS and YPTS |
Y |
NORMAL (no axis) |
|
Z |
Inherited from DAT_TO_SAMPLE |
|
T |
NORMAL (no axis) |
Note:
SAMPLEXYT and SAMPLEXYT_NRST are "grid-changing" functions; the output grid is different from the input arguments. Therefore it is best to use explicit limits on the first argument rather than a a SET REGION command. See the discussion of grid-changing functions.
The XPTS, YPTS, TPTS values must be in the same units as the coordinate axes of the variable DAT_TO_SAMPLE.
