TRN_TR2x

Transform 2-dimensional data

Description:

Apply a compiled {2 → 2} mapping to a set of 2-dimensional data points specified by separate arrays of XIN and YIN coordinates.

Invocation

CALL TRN_TR2x( BAD, NXY, XIN, YIN, ID, XOUT, YOUT, STATUS )

Arguments

BAD = L
Whether the input coordinates may be bad.
NXY = I
The number of data points to transform.
XIN = ?(NXY)
Array of input XIN coordinates.
YIN = ?(NXY)
Array of input YIN coordinates.
ID = I
Identifier for the compiled {2 → 2} mapping to be applied.
XOUT = ?(NXY)
Array to receive the transformed XOUT coordinates.
YOUT = ?(NXY)
Array to receive the transformed YOUT coordinates.
STATUS = I
Inherited error status.
