用matlab中的基本数学包实现-PCA，有助于理解PCA原理。 (Using matlab in the realization of the basic mathematical package-PCA, help to understand the principles of PCA.)

this file contains some m-files about calculating the fractional fourier transform

图书馆索书号文字图像分割matlab源程序。利用了投影法的原理。(Library Call text image segmentation Matlab source code. Use of the principle of the projection method. )

matlab经典时频分析工具箱，短时傅立叶变换（STFT），维格纳分布（WVD）,伪维格纳分布（PWVD）等时频分析方法(Toolbox short-time Fourier transform (STFT) Wigner distribution (WVD) pseudo-Wigner distribution (PWVD) frequency analysis method matlab classic time-frequency analysis)

对摄影测量相机的参数进行标定，拍摄已知精确尺寸的标定板，读入图像，角点检测，标定相机的内外参数，重构标定板与相机的空间结构(The parameters of the photogrammetric camera calibration, accurate recording of known size calibration plate, read the image, corner detection, external camera calibration parameters, calibration plate and the reconstruction of the spatial structure of the camera)

使用matlab编程对于isodata算法的实现(Using matlab programming algorithm for isodata)

衰落信道参数包括多径扩展和多普勒扩展。时不变的多径扩展相当于一个延时抽头滤波器，而多普勒扩展要注意多普勒功率谱密度，通常使用Jakes功率谱、高斯、均匀功率谱。( The fading channel parameters include multipath spreading and Doppler spreading. The time-invariant multipath extension is equivalent to a delay-tap filter, while the Doppler spread should pay attention to Doppler power spectral density, usually using Jakes power spectrum, Gaussian, and uniform power spectrum.)

这是用用 Floyd 算法求任意两点间的最短路径及最短路长的程序 (This is by using Floyd algorithm for arbitrary shortest path between two points and the shortest path length of the procedure)
