matlab codes for solving ODEs, including euler method, RK methods etc, and some examples.

上电后,在BRAKE信号无效,且保护逻辑无输出的情况下? 电机按DIRECTION信号的方向转动? 电流传感放大器采样电机电枢电流,经13脚的RC网络转换为电压值,与D/A转换输出的预定阀值相比较。如果当前的电流使转换的电压值小于阀值?(Power after the BRAKE signal is invalid, and the protection logic no circumstances ? electrical output signals according to the direction of rotation DIRECTION ? current sensing amplifiers motor armature current sample by 13 feet of RC network is converted to voltage value, and D/A conversion output compared to the target threshold. If the current of current to voltage conversion value is less than threshold ?)

极化SAR定标处理的matlab程序，采用最新的Ainsworth算法(Polarization SAR processing matlab calibration procedure, using the latest algorithms Ainsworth)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, the program uses 16QAM modulation, the source of a string of two binary modulation, with the Raised Cosine modulated baseband functions, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot using the minimum Euclidean distance decoding decision, bit error rate calculation.)

matlab中计算数值积分的函数quad的源代码，包括计算原函数没有初等函数表达式的函数积分(matlab function to calculate the numerical integration of the quad' s source code, including the calculation of the original function is not a function of integral primary function expression)

说明：  时域有限差分法求解maxwell方程组。(The finite difference time domain method is used to solve the Maxwell equations)

二次插值法优化，有简单说明，并有一例子。希望大家喜欢(Optimize the second interpolation method, there is a brief description, and there is one example. I hope everyone likes)

BOC调制的相关源码，包括C/Ａ码的产生，Ｄ码的产生，BOC信号调制及解调。非常全面！！！(BOC modulation relevant source, including the C/A code generated, D of the generated code, BOC signal modulation and demodulation. Very comprehensive! ! !)

首先录入一段音频，在通过matlab软件对该音频进行处理，识别出他的波峰波谷，频率变换，然后输出。(First, an audio input, matlab software through the audio processing, identify the peaks and valleys of his, frequency conversion, and output.)

这是一个用matlab编的遗传算法问题。这是一个用matlab编的遗传算法问题。(MATLAB genetic algorithm toolbox and its application, pdg format.)
