PCA MATLAB程序.PCA MAATLAB程序PCA MATLAB程序. (PCA MATLAB program. PCA MAATLAB program PCA MATLAB program.)

对非平稳信号进行分段、截取，再对处理过后的短时信号做短时傅里叶变换，分析其频谱特性，并找到各个时间节点的频率特性，以便分析不同事件段内的声音特征。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysis of the spectrum characteristics and frequency characteristics and find the different time node, in order to analyze the acoustic characteristics of different event period.)

利用matlab模拟光纤中EH11模的模式分布图。(Using matlab simulation mode fiber EH11 mode maps.)

FFT算法C语言实现 和MATLAB中fft函数结果一样的功能(FFT algorithm C language and MATLAB fft function results in the same function)

hilbert变换的程序，输入一个时间序列，既可以得到希尔伯特变换之后的复信号，输出结果是复信号(hilbert transformation)

仿射，图像变换，选取图像四个角点，进行图像变换(Click to select the four corners of the image affine transformation point)

GSA,万有引力算法用于求解智能优化问题,效果特好!!(GSA, Gravitation intelligent optimization algorithm is used to solve problems, good special effects!!)

说明：  本程序是数制转换问题，为十进制数字和罗马数值间的相互转化，本程序用的是函数调用法(This program is the number of system conversion problems, in order to decimal numbers and value of the inter-conversion of Rome, this program using a function call method)

MATLAB对数字信号进行均值滤波，尤其是对数字图像(MATLAB for digital signals mean filter, especially for digital images)

说明：  乘积的最后三位的值只与乘数和被乘数的后三位有关，与乘数和被乘数的高位无关，利用此来求尾数(The last three values of the product only with the multiplier and the multiplicand on the back three, with a high multiplier and the multiplicand has nothing to do, take advantage of this to seek mantissa)
