于慧敏版信号与系统第二版部分自己编的部分matlab程序代码... (YU Hui-min version of the second edition of part of the signal and system part of their series of matlab code ...)

根据一年中前6个月的负荷和电价数据，预测后六个月的电价，并计算精度(According to the first 6 months of the year the load and price data, predict the next six-month price and caculate the accuracy)

压缩包内源码的主要用途是：FSK调试方式的matlab实现(The main purpose of this source is the matlab implementation of FSK debug mode )

matlab实现的读取envi标准格式的代码，对于搞遥感的人来说，很有用(read envi standard file)

kriging模型，用于替代模型，matlab程序，适合数据拟合和预测各种不同条件下的情况(kriging model for alternative model, matlab program for data fitting and projections under various conditions)

说明：  用四阶古典RK方法解初值问题： 取h=1/8。每隔8步打印出数值解与真解的值（u(t)=(t^2)/2-t），画出它们的大致图像，并对产生的结果做出解释。 (with four bands classical RK method for initial value problems : from h = 1/8. Every eight-step numerical solution print and in the true value (u (t) = (t ^ 2)/2-t), they generally draw the images, as well as the results of an explanation.)

complex wave retrieval of bio-medial image

多功能时钟，有图以及程序代码，希望能有所帮助(Multi-function clock, there are maps and code, hoping to be helpful)

说明：  用于实现语音中的对消噪声，本程序用matlab实现(For the voice in noise cancellation, the program achieved with matlab)

本代码是基于牛顿-拉夫逊方法的通用潮流计算。开发环境为Matlab。内含4个m文件和1个代码说明文档。(Power flow calculation based on the Newton-Raphson method)
