interpolates data using the Fourier back transform
There are two way to interpolate data from a given spectrum.
Frist, one can do zero padding to cover
n new data points. Or, secound
the complex amplitude with the associated frequency is taken and evaluated
at given points
xout. Doing that for all frequencies and amplitudes
will give the interpolation.
numeric data vector to be interpolated
numeric data vector with reference points
number of new points
a vector new points
A list with a
y component is returned. The
value evaluates the error of the interpolation with respect to linear approximation
