Example about who to make figures in MAtlab

Adding noise to a signal and simulate the output using matlab

Three test programs provided. These programs just set the matrices to be diagonalized, then call the function repeatly. After each call it printout the transformed matrix, the diagonalizing matrix and the criterion and its decrease.

实现白噪声、正弦信号和带有白噪声的正弦信号的自相关函数的分析。(Achieve white noise, white noise with a sinusoidal signal and a sinusoidal signal of the autocorrelation function.)

this code is used to find short time fourier transform
