一个好用的自然梯度算法程序

说明：  Matlab的数理统计工具箱是Matlab工具箱中较为简单的一个，其牵扯的数学知识是大家都很熟悉的数理统计(Matlab statistics toolbox of Matlab toolbox is a relatively simple, the mathematics involved is that we are familiar with the knowledge of mathematical statistics)

matlab编写的声卡采集声音信号并可以播放出来的gui界面。(matlab write sound card and can play sound signals collected from the gui interface.)

利用Newton迭代法求解f(x)=(x-1)(x-2)(x-3)=x3-6x2+11x-6的根(solve the root of function: f(x)=(x-1)(x-2)(x-3)=x3-6x2+11x-6 by using Newton method)

Designs a linear phase FIR lowpass filter such that it: - minimizes the maximum passband ripple - has a constraint on the maximum stopband attenuation( This is a convex problem. minimize delta s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variables are delta and h (the filter impulse response). )

这是我先根据MATLAB设计的一个FIR滤波器，然后c语言实现，是二阶的，非常好用。(This is my first one under the MATLAB FIR filter design, and then c languages to achieve, is the second order, quite well.)

program related to optmization technique

说明：  用matlab处理图像的入门函数。包括图像读取，图像叠加，增强等。(analysis image signal using matlab method )

OFDM用4QAM调制，simulink仿真(OFDM with 4QAM modulation，with simulink)

该程序是基于matlab开发环境下的二维人脸识别代码(The program is based on matlab development environment of 2 d face recognition code )
