Time-frequency representations with fixed windows or kernels figure prominently in many applications, but perform well only for limited classes of signals.

实现2维分数傅里叶变换的一个重要MATLAB程序，有大的用处(An important MATLAB program 2 dimensional fractional Fourier transform, a very useful)

说明：  计算任意矩阵函数的matlab程序，比较简单(Calculation of arbitrary matrix function matlab procedure is relatively simple)

用来模拟粒子运动的。此元胞自动机需要 一种不同类型的元胞的邻居。此元胞的邻居时刻变化，因此某一个方向运动趋势， 将继续在同一个方向。换言之，此规则保存势头，这是基础的动力仿真。这种邻 居通常被称为 margolis邻居并且这种邻居通常由重叠的 2x2 块的元胞构成。在下 面的表格中，偶数步长时左上方 4 元胞为邻居关系，奇数步长时右下的 4 元胞为 邻居关系。某一特定元胞在每一个时间步长都有3 个邻居，但是具体的元胞构成 了邻居的旋转和反复。(Used to simulate the particle movement. The cellular automaton requires a different type of cell neighbors. This moment of change in a neighbor cell, so a certain direction the trend will continue in the same direction. In other words, this rule saved momentum, which is the foundation of the power simulation. This neighborhood is often called a neighbor and this neighbor margolis usually overlapping 2x2 blocks of cellular composition. In the following table, even when the step left four yuan for the neighbor cell, the odd step 4 when the lower right cell for the neighborhood. A particular cell in each time step has three neighbors, but the specific cellular composition of the neighbor s rotation and repeated.)

矩量法求解半波阵子天线的matlab程序，给出了方向图和增益还有输入阻抗，结果正确，程序规范，程序在实验报告中。(Moment Method time around half-wave antenna matlab procedures, given the pattern and gain and input impedance, the result is correct, procedural norms, procedures in the test report.)

利用最小二乘支持向量机实现无线传感器网络的目标定位1(The use of least squares support vector machine to achieve targeting wireless sensor networks1)

针对均匀线形阵列的阵列波束综合，并把波束综合问题描述成一个凸优化问题。 (For array pattern synthesis problem, and describe it as a convex optimization problem.)

用matlab实现的基于LSB的数字水印算法。算法可以在BMP灰度图像中嵌入水印，水印信息为二值图像，并将其扩展到与原始图像同样大小，进行重复嵌入，提高鲁棒性。同时算法中给出了PSNR值以评价水印图像的效果，(Using matlab realize the number of LSB-based watermarking algorithm. Algorithm can be embedded BMP gray image watermark, watermark information for the binary image, and its expansion to the original image the same size, the repetition of embedding, improve robustness. At the same time algorithm PSNR values are given to evaluate the effect of watermark images,)

现代谱技术及其在路谱分析中的应用 很有用(Modern spectrum technology and its application in the way of the application of spectral analysis is useful)
