DTMF

此程序是关于经济学中布莱克斯科尔斯模型 的matlab实现(This procedure creates a three-dimensional plot showing how gamma changes relative to price for a Black-Scholes option. Recall that gamma is the second derivative of the option price relative to the underlying security price. The plot shows a three-dimensional surface whose z-value is the gamma of an option as price (x-axis) and time (y-axis) vary. It adds yet a fourth dimension by showing option delta (the first derivative of option price to security price) as the color of the surface)

基于短时傅里叶变换的对鼾声信号进行分析，可以计算一些判断OSAHS的指标。(snoring analysis based on STFT)

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

运用Wavelet对图像进行处理！一个不错的小程序哦！可以使用！可供大家参考学习！(The image processing using Wavelet! A good small program! Can use! For your reference study! )
