df?interpcallback

A callback function for user-defined interpolation to be passed into df?interpolateex1d.

Syntax

FORTRAN:

status = dfsinterpcallback(n, cell, site, r, params)

status = dfdinterpcallback(n, cell, site, r, params)

status = dfsInterpCallBack(n, cell, site, r, params)

status = dfdInterpCallBack(n, cell, site, r, params)

Name	Type	Description
n	Fortran: INTEGER(KIND=8) C: long long*	Number of interpolation sites.
cell	Fortran: INTEGER(KIND=8) DIMENSION() C: long long	Array of size n containing indices of the cells to which the interpolation sites in array site belong.
site	Fortran: REAL(KIND=4) DIMENSION() for dfsinterpcallback REAL(KIND=8) DIMENSION() for dfdinterpcallback C: float* for dfsInterpCallBack double* for dfdInterpCallBack	Array of interpolation sites of size n.
r	Fortran: REAL(KIND=4) DIMENSION() for dfsinterpcallback REAL(KIND=8) DIMENSION() for dfdinterpcallback C: float* for dfsInterpCallBack double* for dfdInterpCallBack	Array of the computed interpolation results packed in row-major format.
params	Fortran: INTEGER DIMENSION() C: void	Pointer to user-defined parameters of the callback function.

Name	Type	Description
status	Fortran: INTEGER C: int	The status returned by the callback function: Zero indicates successful completion of the callback operation. A negative value indicates an error. A positive value indicates a warning. See "Task Status and Error Reporting" for error code definitions.
