Function
Provides an intermediate-level mapping function.
Syntax
#include <dx/dx.h>
Array DXMapArray(Array index, Interpolator map, Array *invalid)
Functional Details
This function is lower-level than DXMap but higher than DXInterpolate.
The parameter index specifies an Array containing points to be sampled from the Interpolator map. The result is returned as an Array. If invalid is not NULL, an Array that indicates invalid data in which uninterpolated elements are tagged DATA_INVALID is returned. If an invalid-data Array corresponding to index exists prior to the call to DXMapArray, it should be passed in through *invalid. See DXInterpolate for valid types of index and map data.
Return Value
Returns index or returns NULL and sets an error code.
