fMRI算功能网络。输入资料为90个AAL脑区的BOLD均值，输出为二值网络(fMRI count function network. The input data for AAL 90 brain regions the BOLD mean, output binary network)

采用了小波去噪的思想，课程设计时编写的matlab程序代码，基于分段非线性权重值的Pso算法，搭建OFDM通信系统的框架，进行逐步线性回归，进行波形数据分析,最大似然（ML）准则和最大后验概率（MAP）准则，采用偏最小二乘法。( Using wavelet denoising thought, Course designed to prepare the matlab program code, Based on piecewise nonlinear weight value Pso algorithm, Build a framework OFDM communication system, Stepwise linear regression, Waveform data analysis, Maximum Likelihood (ML) criteria and maximum a posteriori (MAP) criterion, Partial least squares method.)

广义蚁群算法在TSP问题中的实现，得出蚂蚁寻找到的最优路径和收敛过程。(Generalized ant colony algorithm in TSP problems, draw ants to find the optimal path and the convergence process.)

在频率域实现信号的频移，然后再变换回时间域的信号(In the frequency domain, the frequency shift signal is achieved, and then transformed back into the time domain signal)

说明：  这个程序可以产生一个6阶的低通巴特沃思滤波器，截止频率是45Hz，你也可以用它来对信号进行滤波，并比较滤波前后的信号功率谱。(This program can generate a six-order low-pass Butterworth filter, cut-off frequency is 45Hz, you can also use it to filter the signal and to compare before and after filtering the signal power spectrum.)
