[matlab] STFT_SWT_ST_matlab-files DL : 0: STFT和ST变换的基本函数，和一个stft的一个例程-This code computes the Stockwell transform (S-Transform) of a one dimensional series without for loop, thereby making it computationally fast and simple. S-Transform was proposed in 1996. A nice tutorial on S-Transform can be found here: djj.ee.ntu.edu.tw/S_Transform.pdf? File Information Description The present code is a Matlab function that provides a Short-Time Fourier Transformation (STFT) of a given signal x(n). The algorithm is similar to that of Matlab command “spectrogram”. The result is: 1) stft- a matrix with complex stft coefficients with time across columns and frequency across rows 2) f- frequency vector 3) t- time vector. swt Discrete stationary wavelet transform 1-D. swt performs a multilevel 1-D stationary wavelet decomposition using either a specific orthogonal wavelet ( wname see WFILTERS for more information) or specific orthogonal wavelet decomposition filters.
