Detailed Description

approx1 interpolates data along the first dimensions.

It has three options for the type of interpolation to perform:

• Nearest neighbor - AF_INTERP_NEAREST
• Linear interpolation - AF_INTERP_LINEAR
• Bilinear interpolation - AF_INTERP_BILINEAR
• Cubic interpolation - AF_INTERP_CUBIC

Function Documentation

AFAPI af_err af_approx1	(	af_array *	out,
		const af_array	in,
		const af_array	pos,
		const af_interp_type	method,
		const float	offGrid
	)

C Interface for signals interpolation on one dimensional signals.

Parameters

[out]	out	is the array with interpolated values
[in]	in	is the input array
[in]	pos	array contains the interpolation locations
[in]	method	is the interpolation type, it can take one of the values defined by the enum af_interp_type
[in]	offGrid	is the value that will set in the output array when certain index is out of bounds

Returns

AF_SUCCESS if the interpolation operation is successful, otherwise an appropriate error code is returned.

AFAPI array af::approx1	(	const array &	in,

Parameters

[in]	in	is the input array
[in]	pos	array contains the interpolation locations
[in]	method	is the interpolation type, it can take one of the values defined by the enum af_interp_type
[in]	offGrid	is the value that will set in the output array when certain index is out of bounds

Returns

the array with interpolated values
