mathematica code for gaussian horn design. It can give the exact shape of gaussian for specific material, especially helpful for ultrasonic horn design.

Myplotyy plots different data sets with a common x-axis allowing for different y-axes in one figure. The properties of every curve can be adjusted indivually, such as linear or logarithmic scale, normal or reverse scale, confidence intervasl, colours, curve labeling

findEnergy.m 计算出图像的梯度图 findSeamImg.m 计算出所有可能的竖直缝 findSeam.m找出能量最小的一条竖直缝 removalMap.m将需要删除的N条竖直缝存储起来并按照索引逐条删除 SeamCut.m将选中的缝一条条的删除 SeamPlot.m在图中画出要删除的缝 Testseam.m调用以上函数的主程序(FINDENERGY creates an gradient img from a given RGB or grayscale image. FINDSEAMIMG finds the seam map from which the optimal (vertical running) seam can be calculated. FINDSEAM returns a column vector of coordinates for the pixels to be removed (the seam). SEAMPLOT takes as input an image and the SeamVector array and produces an image with the seam line superimposed upon the input image, x, for display purposes. SEAMCUT takes as input a RGB or grayscale image and SeamVector array to find the pixels contained in the seam, and to remove them from the image. REMOVALMAP takes a given image and finds the ordered set of (vertical) seams that are removed from an image and returns them in an array, where the Nth column in the array corresponds to the Nth seam to be removed.)

多重信号分类（MUSIC）算法，将信号分为信号子空间和噪声子空间，利用特征值估计频率(Multiple signal classification (MUSIC) algorithm, the signal is divided into signal subspace and noise subspace, the use of eigenvalues to estimate the frequency)

用Matlab做的神经网络的BP算法做识别字符，该程序比较容易读(Done with Matlab neural network BP algorithm to do character recognition, the program easier to read)

chua matlab model simple analysis A solution of these equations (I3,V2,V1)(t) starting from an initial state (I3,V2,V1)(0) is called a trajectory of Chua s oscillator. This function uses a RungeKutta integration method optimised for the chua paradigm Reference: ABC - Adventures in Bifurication & Chaos ... Prof M.P Kennedy 1993

给定极化状态的相位描述子和幅度描述子，绘制该极化状态的poincare功率球。源代码是matlab子函数，输入参数两个：极化状态的幅度描述子和相位描述子。还有一张示例图(Given the polarization state of the phase and amplitude descriptors descriptors, to draw the polarization state poincare power ball. Functions matlab source code, two input parameters: the polarization state and phase amplitude descriptor descriptor.)

this source code is very well
