清华大学数值计算和数学实验建模的幻灯片与MATLAB源代码(Tsinghua University, numerical experiments and mathematical modeling of the slide with the MATLAB source code)

输入信号的时域和频谱分析 输入信号为ft=[5cos(600*pi*t)+4cos(90*pi*t)+9]/18 输入信号为高频和低频信号的叠加：高频300Hz，低频45Hz( Of the input signal in time domain and spectral analysis of the input signal is ft = [5cos (600* pi* t)+4 cos (90* pi* t)+9]/18 input signal for the high-frequency and low frequency signal superimposed: frequency 300Hz, 45Hz low frequency)

Part of the license plate recognition locator feature, STM32 all the information produced by the MP3, The final weight matrix is ??the filter coefficient.

this matlab function finds peaks of a plot. it takes a coordinate matrix as an input. also removes redundent peaks (for instance, in case of a step plot, it finds one peak)

一个非常简易的均线策略，仅作展示用，高手绕行。 5日均线上穿20日均线，做多1手；5日均线下穿20日均线，做空1手； 其中这里上穿、下穿如下定义： 上穿定义：MA5当天大于MA20，前一天MA5位于MA20之下 下穿定义：MA5当天小于于MA20，前一天MA5位于MA20之上 测试数据：IF1112 （2011/5/3-2011/12/8）每日收盘价。 初始资金 50万(a sample back testing matlab code based on ma)

在matlab环境下编写的非线性控制工具箱,希望对大家有用(Written in the matlab environment, nonlinear control toolbox, we hope to be useful)

频数统计，能够统计变量的出现的频数，还比较好用。(Frequency statistics, the statistical variables appear frequency, but also relatively easy to use.)

Mackey-Glass时间序列预测建模问题，建立了四输入一输出、具有3层结构的MLP人工神经网络，实现了函数逼近的功能。(Mackey-Glass time series prediction modeling, the establishment of a four-input one output, with a 3-layer MLP artificial neural network architecture to achieve a function approximation functions.)

This script shows how to use the GA using a float representation.Crossover Operators & Mutation Operators are used.

to find the discrete fourier transform using the fast fourier algorithm, any sequence of lengths which are multiples of 2 simply append zeros to satisfy this requirement
