crypto

说明：  使用matlab程序实现了由随机序列到码元电平、m序列直接扩频解扩、qpsk调制解调，射频调制解调一个完整的qpsk系统过程(Matlab program to use by the random sequence to the symbol level, m direct sequence spread spectrum despreading, qpsk modulation and demodulation, RF modulation and demodulation of the QPSK system, a complete process)

这个程序用来模拟windows计算器,为薜定宇老师<<科学运算语言MATLAB5.3程序设计与应用>>的习题而做(It is suitable for beginners to master matlab deep into the second developed a good teaching examples of great reference value)

股票数据绘图, suppose we place a limit order to sell at limit prices vol is the annual volatility of the stock and price is the current price. vol is output from estvol assumes we input Open, Close, High, Low, daily prices and the price( suppose we place a limit order to sell at limit prices vol is the annual volatility of the stock and price is the current price. vol is output from estvol assumes we input Open, Close, High, Low, daily prices and the price)
