color feature extraction for target tracking and particle filter

通过一系列教学实例，帮助学生很好的理解matlab中的符号运算实现微分、积分（定积分与不定积分）、极限、级数、绘图等常用功能，几乎可以推导高数中的绝大部分公式，也可用于理论公式推导。(Through a series of teaching examples to help students a good understanding of symbolic computation matlab achieve differentiation, integration (with the definite integral indefinite integral), ultimate, series, graphics and other commonly used functions can be derived almost most of the high number of formulas can also be used to derive theoretical formulas.)

说明：  MATLAB 频谱分析的经典仿真，详细的源程序及仿真文件 (MATLAB spectral analysis of the classical simulation of the detailed source code and simulation files)

A numerically-controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e. clocked), discrete-time, discrete-valued representation of a waveform, usually sinusoidal.

用matlab实现对语音信号的短时分析，包括清音和浊音的判决，基音周期的估计，实验报告。(use matlab language analysis the speech signal,contains the analysis for unvoiced sound and voiecd sound.)

calculate gauss into two vectors

[sigma,mu,A]=mygaussfit(x,y) [sigma,mu,A]=mygaussfit(x,y,h) this function is doing fit to the function y=A * exp( -(x-mu)^2 / (2*sigma^2) )
