AST_TRAN1

Transform 1-dimensional coordinates

Description:

This routine applies a Mapping to transform the coordinates of a set of points in one dimension.

Invocation

CALL AST_TRAN1( THIS, NPOINT, XIN, FORWARD, XOUT, STATUS )

Arguments

THIS = INTEGER (Given)
Pointer to the Mapping to be applied.
NPOINT = INTEGER (Given)
The number of points to be transformed.
XIN( NPOINT ) = DOUBLE PRECISION (Given)
An array of coordinate values for the input (untransformed) points.
FORWARD = LOGICAL (Given)
A .TRUE. value indicates that the Mapping s forward coordinate transformation is to be applied, while a .FALSE. value indicates that the inverse transformation should be used.
XOUT( NPOINT ) = DOUBLE PRECISION (Returned)
An array into which the coordinates of the output (transformed) points will be written.
STATUS = INTEGER (Given and Returned)
The global status.
