Return matrix of all possible k indexes, it is C(n,k) variants

主要用MATLAB对图像惊进行处理，对图像进行直方图处理 给出均衡前后的图形很有实用(Main MATLAB to image surprised processing, the image histogram equalization before and after the treatment given graphics is practical)

Face Recognition using wavelet transform in matlab

说明：  基于MATLAB的语音信号处理之滤波器设计(MATLAB-based speech signal processing of the filter design)

本程序仿真了正交频分复用的调制与发射，其中包括循环前缀，FFT变换，白噪声信道模拟等部分，最后得出不同信噪比先的系统误码率。(This program simulates the orthogonal frequency division multiplexing modulation with the launch, including the cyclic prefix, FFT, white noise channel analog part of the conclusion that a different signal to noise ratio before the BER.)

对原始正弦信号进行傅里叶变换与逆变换并给出结果(Fourier transform and inverse transform the original sinusoidal signals and gives results)
