Description: 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. Platform: |
