Vec<T> itpp::lininterp	(	const Vec< T > &	v,
		double	f_base,
		double	f_ups,
		int	nrof_samples,
		double	t_start = 0
	)			[inline]

Upsample vector v to achieve f_ups frequency using linear interpolation.

Author:

Adam Piatyszek

This function performs upsampling of vector v to achieve nrof_samples samples at f_ups frequency starting from the sample at t_start time. The frequency of input samples stored in the vector v is defined by the f_base parameter.
