am mod used to modulate an am signal

非线性加速度法计算单自由度体系地震时程反应,刚度矩阵，地震反应(Linear acceleration method to calculate the single degree of freedom system earthquake history response, stiffness matrix, seismic response)

主要实现的是2*2用户，采用qpsk调制，实现仿真模拟图(The main achievement of 2* 2 users, qpsk modulation, simulation Figure)

this file contains many programs of wavelet algorithm

CDMA different techniques are used to use it modulate and demodulate

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 仅含有Ez,Hx,Hy分量 (the two-dimensional program TM wave FDTD simulation procedure set up by PML absorbing boundary conditions for containing Ez , y, Hy weight)

最速下降法又称为梯度法，是1847 年由著名数学家Cauchy 给出的，它是解析法中最古老的一种，其他解析方法或是它的变形，或是受它的启发而得到的，因此它是最优化方法的基础。这里给出其Matlab源程序。(The steepest descent method, also known as gradient method, was in 1847 given by the famous mathematician Cauchy, it is the oldest analytical method one, other analytical method or its variants, or inspired by it obtained and therefore it is the basis for the optimization method. Here are its Matlab source.)

说明：  自相关算法的程序，可以运行的，本人认真研究，编写出来的(Autocorrelation algorithm that can run, I seriously study, written by)

自己写的一个车牌定位matlab程序，希望对大家有用。(Himself wrote a matlab license plate location process, in the hope that useful to everyone.)

Algorithms For Programmers Ideas And Source Code英文的，希望对大家有帮助。()
