完成图像的比例缩放，可以按照需要完成对图像的大小设置 (To complete the image scaling, image size is set in accordance with the need to complete)

Pattern search (also known as direct search, derivative-free search, or black-box search) is a family of numerical optimization methods that does not require a gradient. As a result, it can be used on functions that are not continuous or differentiable. One such pattern search method is "convergence" (see below), which is based on the theory of positive bases. Optimization attempts to find the best match (the solution that has the lowest error value) in a multidimensional analysis space of possibilities.

说明：  我写的matlab 的ar模型代码，很实用，希望对你有帮助(I wrote the ar model matlab code, very useful, want to help you)

KALMAN filter for linear time invariant estimation

频域分解法在MATLAB中的应用，模态参数识别，先滤波，再FDD(frequency domain decomposition)

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％，不加入噪声，进一步生成某个特定的中频信号。(Matlab generated using GPS C/A code base band signal. (1) generation of satellite PRN number is " 5" a set of C/A code (2) loop generates 25 of the navigation data, GPS time can fill a fixed known value (3) to generate C/A code spread spectrum signal, each C/A code chip gives the four sampling data (4) baseband signals using square wave signal, level 0 and 1, 50 duty cycle, not to join the noise generated further a specific frequency signal.)

本程序是用于天线阵列波束波束形成的 LCMV算法，算法给出了误码率曲线，可以看出LCMV算法在高信噪比时误码率很小。 (this procedure is used for beam antenna array beam forming the Virus algorithm, the algorithm is given BER curves, Virus algorithm can be seen in the high signal-to-noise ratio at the bit error rate is very small.)

室内无线定位技术，基于比例圆算法的matlab仿真程序(Indoor wireless positioning technology, based on proportional circle algorithm matlab simulation program)

语音的端点检测是根据语音的特征来进行了，本文根据语音不同帧之间能量的不同，一帧一帧的进行比较(Speech endpoint detection is based on the characteristics of voice, different voice between the different frames of energy, a one to compare)
