ZoomFFT

这里有拟合还有误差分析的基本所有函数，是经济学学习过程中的(There is also the error of fitting all the basic functions of the learning process in economics)

说明：  本源程序为采用IV辅助变量算法法进行供电负荷预测的，后面还自带了进行模型检验的部分，很适合电力专业的学生学习使用(The source code for the algorithm using method IV auxiliary variable power load forecasting, the model behind the test also comes with some very suitable to use the power of professional learning)

本程序实现2维TM波FDTD仿真 此程序用PML设置吸收边界条件 FDTD_2D_PML 仅含有Ez,Hx,Hy分量 (The procedure to achieve 2-D TM wave FDTD simulation of this process with the PML absorbing boundary condition FDTD_2D_PML set contains only Ez, Hx, Hy component)

说明：  isar 成像例程，可以使用，距离多普勒成像过程(ISAR imaging routine, available, range Doppler imaging process)

噪声环境下语音信号的增强,噪声环境下语音信号的增强,噪声环境下语音信号的增强(The enhanced speech signal in noisy environment )

matlab中文教程，含演示例程，供初学者参考学习。(Chinese tutorial matlab, including demonstration routine reference for beginners to learn.)

基于MATLAB软件下的QPSK 调制解调(MATLAB-based software under the QPSK modulation and demodulation)

说明：  本程序用matlab生成白噪声，并且基于一个离散线性随机系统的模型生成了y(k)和x(k)，绘制出了x(k|k-1)和x(k)的对比曲线，求出了提前一步预报的误差协方差阵的稳定值(the procedures used Matlab generate white noise, and on a discrete linear stochastic systems model generated y (k) and x (k), mapping out the x (k | k-1) and x (k) contrast curves, get a step ahead forecasting error covariance matrix of stable value)
