Description: randgen(mu,mu1,mu2,cov1,cov2,cov3) = Random generation of Gaussian Samples
in d-dimensions where d = 2
mu, mu1, mu2 = (x,y) coordinates(means) that the gaussian samples are centered around
cov1, cov2, cov3 are the covariance matrices and will vary changing the
shape of the distribution, example: cov = sigma^2*Identity Matrix, where sigma^2 = a scalar
N = the number of gaussian samples used are provided as user input,
A test set of N/2 and a training set of N/2 gaussian samples is also generated
Output is directed to the command window and a plot of the distributions are generated

Description: The S transform is variable window of short time Fourier transform (STFT) or an
extension of wavelet transform (WT). It is based on a scalable localizing Gaussian
window and supplies the frequency dependent resolution. In this tutorial, we
introduce the fundamental function of S transform and the generalized S transform.
Furthermore, we present some applications of S transform: seismogram analysis,
analysis of engine induction noise in acceleration, and power quality analysis. Then
compare the result of S transform with other time-frequency analysis and exhibit some
different windows of S transform.
