The conventional Goertzel Algorithm can be used to compute individual DFT coefficients. In case we need to compute some values of DTFT (that means, non-integer multiples of the fundamental frequency), slight modification must be done.
There are two files: the conventional and generalized Goertzel algorithm. No toolboxes needed.
The algorithm and its derivation is described in the article accesible at
