运用Perona-Malik各向异性扩散模型对3d图像进行平滑去噪。此方法可以有效的抑制高斯噪声，并保护图像的边缘特征。(The use of Perona-Malik anisotropic diffusion model for smooth 3d image denoising. This method can effectively suppress Gaussian noise and to protect the image of the edge feature.)

可以产生二元正态分布随机数，绘制二元正态分布随机数的频数直方图(produce two-variables normal distribution random data, and plot frequency picture according the data.)

这个程序是用改进平方根法对线性方程组进行求解，要求系数矩阵必须是对称正定矩阵(This procedure is used to improve the square root method to solve linear equations, requiring the coefficient matrix must be symmetric positive definite matrix)

Matlab手写文字识别源代码 这个Demo展示手写文字识别的各个步骤，包括图像的预处理、裁剪、大小转换、人工神经网络训练和识别等等。(Handwritten character recognition Matlab source code of this Demo display of handwritten character recognition of the various steps, including image preprocessing, cutting, size conversion, artificial neural network training and recognition and so on.)
