The present code is a Matlab function that provides an interpolation of a given signal in the time domain via zero-padding in the frequency domain. The algorithm is similar to that of the Matlab command “interpft”.
An example is given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.

The code is based on the theory described in:

Nice work; it is better than understanding interpft in MatLAB. I tested with my own code and it gives exactly same results. The issue with this interpolation is that beginning and end values become erroneous when non-periodic signal is used.
