说明：  在matlab中实现主成分分析方法，并使用FERET库的灰度图像进行测试(This package implements basic Principal Component Analysis in Matlab and tests is with grayscale portion of the FERET database. )

关于图像的灰度处理，翻转，很不错的源码还有界面。(On the gray image processing, flip, very good source are the interface.)

This is a file.m (Matlab) with the Lagrange method

Jacobi迭代法和Gauss-Seidel迭代法Matlab程序，可用于求解线性方程组(Jacobi iteration method and Gauss- Seidel iterative method Matlab procedures, can be used to solve the linear system of equations)

Rotates an image by the angle degrees in the % CCW direction. Degrees may be any number. % The function will put degrees in the range 0 % to 360 degrees and then into a range of -45 to 45 % degrees after performing elementary 90 degree rotations.(Rotates an image by the angle degrees in the % CCW direction.

采用matlab编写的利用共轭梯度法求解矩阵方程(Prepared using matlab conjugate gradient method using matrix equation)

本代码在matlab下实现rs编码并加入噪声 以及纠错编码(Under this code in matlab coding realize rs and add noise and error correction coding)

说明：  用matlab程序实现，生成谢尔宾斯基图像。(Program for using matlab to generate Sierpinski image.)

some resources for matlab

本程序实现QPSK信号，通过瑞利信道后的各部分星座图(The program QPSK signal, Rayleigh channel through each part of the constellation after)
