Matlab code for for Fourier Transform

A doc about spectral analysis using matlab

对图形图像进行处理，使图形图像配准，更为准确(The graphic image processing, the graphics image registration, more accurate)

对信号进行小波包分解，得到节点的小波包系数。然后对每个节点系数进行重构。(Wavelet packet decomposition is used to get the wavelet packet coefficients of the nodes. Then the coefficients of each node are reconstructed.)

求多项式的值y=ployval(p,x)：计算x点处多项式值 有理多项式 有理多项式求导：[q,r]=polyder(a,b)(matlab DESIGN)

线性方程组LU分解直接解法，GS迭代、夹克比迭代、SOR迭代等Matlab代码(linear simultaneous equations)

matlab神经网络工具箱，数学建模中常用到的知识，必备。(matlab neural network toolbox, used mathematical modeling to knowledge, essential.)

说明：  无刷双馈电机模型，开环仿真总是出错，希望大家帮帮忙看看啊(BDFM model, open-loop simulation is always wrong, hope that we help out and take a look at ah)

Matlab implementation of image segmentation/edge preserving filtering algorithm

this is watermark source code. it is good for making programming
