Detailed Description

Vector scaling function.

This object, inspired from the scale object in FTS, the jMax engine, scales the values of a vector according to an affine function defined as follow:

Function Documentation

void aubio_scale_do	(	aubio_scale_t *	s,
		fvec_t *	input
	)

scale input vector

Parameters:

s	scale object as returned by new_aubio_scale
input	vector to scale
