用MATLAB合成歌唱祖国，包括初步与简单改变（包络）(Ode to the Motherland synthesis using MATLAB, including the initial and simple to change (the envelope))

This code computes the approximation of the convolution integral (*) between two functions, f(t) and g(t), sampled at the times t1,t2,...,tm (unit spacing), via the trapezoidal quadrature rule. To compute the integral with other than unit spacing, multiply the result by the spacing increment.

总结了数学建模中的常用算法，比较实用，可以借鉴(describ matlab)

在信号分析中，我们常把信号进行矢量分解，也就是将信号分解为频率相同、峰值幅度相同但相位相差90的两个分量。该程序实现将信号分解为I路和Q路。(In signal analysis , we often decompose the signal vector , that is, the signal is decomposed into the same frequency , the peak amplitude of phase 90 of the same, but the two components . The program implementation will signal into I and Q branches .)

this is a sample code for rat slam in matlab code.
