Webis a MATLAB toolbox – modeled after commercial toolboxes. Functionally, it becomes a part of the MATLAB toolbox set so that AT functions can reuse tools from other toolboxes, for instance optimization and control. AT is an open-ended collection of tools – MATLAB functions and scripts arranged in functional groups as opposed to one giant engine. WebApr 5, 2024 · 3) Windowing operation is just taking W samples and multiplying by them by the window size W sample by sample x [ n] w [ n] 0 ≤ n ≤ W − 1. After FFT, you move the window by step size of L samples and do the windowing and FFT again to get the spectrum at next time interval. L will determine how smoothly your spectrogram varies across time.
