Then this is a question for a C forum and off-topic here.
Did you search e.g. for "fft C" in the net already? You will find many implementations. The creation of a C-mex wrapper is easy also and Matlab includes some useful examples. Search in the documentation.

MATLAB has support for fftw which is open source from MIT and also available in an open source C library at https://www.fftw.org/.
