说明：  matlab中，对语音信号分帧，以实现对语音信号的短时平稳过程的分析。(enframe)

我上机实验时在matlab环境上编写的一个关于滤波器的程序文件。(This is a file about filter builded in matlab.)

二维谱相关函数计算,未形成3d视图，但做了具体到每个循环频率的剖面图(Computing Spectral Correlation Function)

从网格划分软件Gambit读取1维网格的Matlab程序，来自《节点间断迦辽金方法》一书(Matlab program read from the meshing software Gambit one-dimensional grid, from the node discontinuous Galerkin method, " a book)

Contrast improuvement using INT operators Ion grayscale image

MFCC参数计算，也可进行语音信号处理。 本程序需要调用voicebox工具箱中的melbankm.m程序得到Mel频率滤波器组(MFCC parameters, but also for voice signal processing. This procedure required to call VoiceBox toolbox melbankm.m procedures Mel frequency filter bank)

本程序为用matlab实现高等数学中的二次曲面图像的绘制(the procedure for senior math figure)

说明：  光伏发电功率主要受太阳辐照度影响，所以准确预测太阳辐照度对光伏功率预测十分重要。程序采用小波分解先对辐照度数据进行分解，然后再用bp神经网络对分解的辐照度数据分别预测，再组合作为最后的预测结果。(Photovoltaic power generation is mainly affected by solar irradiance, so accurate prediction of solar irradiance is very important for photovoltaic power prediction. The program uses wavelet decomposition to decompose the irradiance data, then uses BP neural network to predict the decomposed irradiance data separately, and then combines them as the final prediction result.)

说明：  生物地理学优化算法代码，用与求解测试函数，内含对比算法PSO，GA，等多种算法代码(Biogeography optimization algorithm code, use and solve test function, including contrast algorithm PSO, GA, and other algorithm codes)
