MATLAB program that implements a DIT Radix‑2 FFT using adaptive base‑case switching and heuristic twiddle‑factor caching. In this version the input is provided as a 16‑point sequence with 16‑bit integer values (using MATLAB’s int16 type). Before processing, the program converts the input to double precision (since MATLAB’s FFT arithmetic is performed in double precision).
