MATLAB source code for computing Discrete Fourier Transform (DFT), a mathematical method that converts finite sequences into frequency domain representations. DFT is widely used in signal processing, image processing, and related fields. This source code implements the DFT algorithm using MATLAB's matrix operations and iterative approaches, efficiently transforming input finite sequences into their frequency domain counterparts. The implementation includes key functions for handling complex numbers and calculating Fourier coefficients through summation of exponential terms. By utilizing this code, developers can gain deeper understanding of DFT's underlying principles, examine the transformation process step-by-step, and apply it to various projects involving spectral analysis and frequency domain manipulation. The code demonstrates proper handling of sequence length, frequency bin calculations, and output normalization for accurate frequency representation.
