P_out_width

在MATLAB环境下，以上代码通过编译。P0311：利用巴特沃斯（Butterworth）低通滤波器对受噪声干扰的图像进行平滑处理 P0312：利用巴特沃斯（Butterworth）高通滤波器对图像进行锐化处理(In the MATLAB environment, the above code through the compiler. P0311: the use of Butterworth (Butterworth) low pass filter on the image noise by smoothing treatment P0312: the use of Butterworth (Butterworth) high-pass filter for sharpening images treatment)

本程序是用matlable求任意一个二维矩阵的边界矩阵，与C和C++不同，这里不只用循环，比C和C++要方便快的多。(This procedure is arbitrary matlable seeking a two-dimensional matrix of the boundary matrix, with C and C is different here, not only by cyclic than C and C should be faster and more convenient.)

本程序实现对图像的增强，通过模糊增强算法，使图像的边缘信息更加明显，图像出来，能够更好的处理高频信息(This procedure to achieve an image enhancement, through the fuzzy enhancement algorithm, so that the edge of the image information more clearly, the image out, better able to deal with high-frequency information)

MATLAB在自动控制系统中的仿真应用，电子书，内容很有价值，本站尚没有此书。(MATLAB in Simulation of automatic control system application, e-books, valuable content, this site has not this book.)

基于omp重构算法的压缩感知的正交化高斯测量矩阵的图像压缩算法(Based on omp restructuring algorithm compression sensation orthogonalization Gauss measurement matrix image compression algorithm )

结合上传的LMFnlsq2testPDF.rar文件，可以轻松的明白本程序的实现步骤以及编程思想。(Combination of upload LMFnlsq2testPDF. Rar file, can easily understand the program implementation steps and the programming ideas.)

It is a very useful matlab program to plot a 3D graph by using sfunction and it shows how to use multiplexur for x, y and z signals. Enjoy it and good luck.
