The conventional Goertzel Algorithm can be used to compute individual DFT's coefficients. In case we need to compute some values of DTFT (that means, non-integer multiples of the base frequency), slight modification must be done.
The link contains two files: the conventional and generalized Goertzel algorithm for MATLAB (no toolboxes needed).
