Matlab permutation matrix

基于MATLAB实现水下4fsk调制解调(Based on MATLAB realization underwater 4fsk modem)

tasks assigned in matlab

基于matlab的BPSK的高斯白噪声调制解调 相信对大家有用(Based on matlab for BPSK modulation and demodulation of Gaussian white noise, I believe for all of us)

MATLAB数值运算，很实用的MATLAB教程，希望对大家有些帮助。(MATLAB numerical computing, MATLAB is very useful tutorial, we want some help.)

有关FPNC的一些解码程序，有一定的注释，便于理解整个译码过程(some codes about FPNC_Matlab_ decoding)

bp网的程序，设计一个神经网络字符分类器对英文字母进行分类。输入向量含有16个分量，输出向量分别用设置的T向量，还不完善，有待改进(bp network program, character design a neural network classifier to classify the English alphabet. Input vector contains 16 components, respectively T vector output vector set, not perfect, needs improvement)

说明：  计算两个离散变量x和y的条件熵z = H（x | y）。 with Input：两个相同长度的整数向量 有益于学习(Compute conditional entropy z=H(x|y) of two discrete variables x and y. with Input: of two integer vector of the same length good for learning)

按照给定指标采用模拟低通滤波器（巴特沃思低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(Indicators in accordance with a given analog low-pass filter (Butterworth low-pass) to approximate the ideal analog low-pass filter, and then through the bilinear transformation method of digitizing analog filters, the digital filter.)

研究生一门课程的小作业，很全，是关于模拟退火算法的(Postgraduate course of a small job, very full, the simulated annealing algorithm)
