matlab课件 包含10讲 解压后17M(Courseware includes 10 speakers matlab after decompression 17M)

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)

根据加噪声的音乐信号，设计合适的滤波器，对原有信号进行滤波，去除噪声，实现滤波功能。(According to the signal plus noise music, design the appropriate filter, the original signal is filtered to remove noise, the filtering function.)
