Function Documentation

splineexpl()

void splineexpl	(	real *	f,
		int	n,
		int	bc,
		real *	c )

Calculate explicit cubic spline interpolation coefficients in 1D.

This function calculates the explicit cubic interpolation coefficients for a 1D data set using one of two possible boundary conditions. Function returns a pointer to coefficient array.

Parameters

f	1D data to be interpolated
n	number of data points
bc	boundary condition flag
c	array for coefficient storage, has length 4*n

NATURAL (Second derivative is zero at both ends)

PERIODIC (Function has same value and derivatives at both ends)
