用于解反问题的共轭梯度法，对于Ax=b，输入矩阵A，列向量b，以及迭代步数k，可求的列向量x(Solution of inverse problems for the conjugate gradient method, for Ax = b, the input matrix A, the column vector b, as well as the number of iterations k, rectifiable column vector x)

this is the active noise developed by running an active sysetem

根据一组样本数据的均值和协方差矩阵随机产生正态分布以及对数正态分布的任意规模的样本数据。(According to a set of sample data mean and covariance matrix randomly generated normal and lognormal distribution of the sample data of any size.)

基于方差一致性准则对图像进行四叉树分解！(variance quadtree)

matlab无约束优化问题的信赖域算法程序-matlab trust region method(matlab trust region method matlab trust region method matlab trust region method)

Bresenham algorithm, platform matlab.

文章的代码主要讲述椭圆型方程五点差分格式。用MATLAB软件来实现，大大提高了算法的精确度。(The code article focuses on five difference scheme for elliptic equations are considered. Use MATLAB software to realize, greatly improve the precision of the algorithm.)

LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。 (LDPC Coding with PSK modulation in Rayleigh fading channel Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements. In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated.
