array af::interp	(	array &	X,
		array &	Y,
		array &	Xi,
		unsigned	method = 0
	)

Interpolation in one dimension (1D).

Parameters:

[in]	X	Domain indices ignored and assumed 0...Y.elements()-1
[in]	Y	Function values (range)
[in]	Xi	Domain values at which to interpolate Y
[in]	method	Currently only supports 0='linear'

Returns:

array same size as Xi with values interpolated from Y

array af::interp	(	array &	X,
		array &	Y,
		array &	Xi,
		float	init,
		unsigned	method = 0
	)

Interpolation in one dimension (1D).

Parameters:

[in]	X	Domain indices ignored and assumed 0...Y.elements()-1
[in]	Y	Function values (range)
[in]	Xi	Domain positions at which to interpolate Y
[in]	init	value assumed when interpolating outside domain
[in]	method	Currently only supports 0='linear'

Returns:

array same size as Xi with values interpolated from Y

array af::interp	(	array &	X,
		array &	Y,
		array &	Z,
		array &	Xi,
		array &	Yi,
		unsigned	method = 0
	)

Interpolation in two dimensions (2D).

Parameters:

[in]	X	domain indices in first dimension, same size as Z, ignored and assumed 0...Z.dims(0)-1
[in]	Y	domain indices in second dimension, same size as Z, ignored and assumed 0...Z.dims(1)-1
[in]	Z	function values (range)
[in]	Xi	X domain positions at which to interpolate Z
[in]	Yi	Y domain positions at which to interpolate Z
[in]	method	Currently only supports 0='linear'

Returns:

array same size as Xi and Yi with values interpolated from Z
