### AST_POINTINREGION

Tests if a single point is inside a Region

#### Description:

This routine returns a logical value indicating if a supplied point is inside a supplied Region.

#### Invocation

RESULT = AST_POINTINREGION( THIS, POINT, STATUS )

#### Arguments

##### THIS = INTEGER (Given)
Pointer to the Region.
##### POINT( $\ast$ ) = DOUBLE PRECISION (Given)
An array holding the axis values of the point to be tested. The number of values in this array should match the number of axes in the supplied Region.
##### STATUS = INTEGER (Given and Returned)
The global status.

#### Returned Value

##### AST_POINTINREGION = LOGICAL
.FALSE. if the point is outside the Region, and .TRUE. otherwise.

#### Notes:

• If the supplied value is AST__BAD on every axis, then .FALSE. is always returned.

• If many points need to be tested, then it is usually more efficient to use the Region as a Mapping to transform all the points. This can be done using one of the Mapping transformation methods (AST_TRAN$<$X$>$). If a transformed axis value is AST__BAD then the corresponding input point is outside the Region.

• .FALSE. will be returned if an error occurs.
