intro 2 matlab which gives fundamentals about matlab

说明：  雷达建模仿真的一些基本程序，主要有目标跟踪，信噪比，后向反射系数等雷达系统建模仿真程序(Radar modeling and simulation of some basic procedures, main target tracking, radar system signal to noise ratio and other process modeling and simulation)

JPEG_LS无损压缩的算法，此算法经常用于高质量的算法研究，希望大家好好利用。也希望群主给我加下载点数。(JPEG_LS lossless compression algorithm that is often used in high-quality research algorithms, we hope to take advantage of. I also hope that the main group to add download points.)

简单的用PCA实现人脸识别的matlab程序(Face recognition using PCA to achieve)

说明：  图像的双线性插值放大算法中，目标图像中新创造的象素值，是由源图像位 置在它附近的2*2 区域4 个邻近象素的值通过加权平均计算得出的。 双线性内插 值算法放大后的图像质量较高，不会出现像素值不连续的的情况。然而次算法具 有低通滤波器的性质，使高频分量受损，所以可能会使图像轮廓在一定程度上变 得模糊。 (Bilinear interpolation algorithm to enlarge the image, the target image in the newly created pixel value is determined by the source image position in its area near the 4 2* 2 the value of neighboring pixels calculated by the weighted average. Bilinear interpolation algorithm to enlarge the image quality after the high pixel value does not appear the situation is not continuous. However, sub-algorithm has low-pass filter nature of the damage to the high frequency components, it may make the image contour to some extent become blurred.)

SPWM MATLAB/simulink仿真模型，希望感兴趣的同学相互交流 (SPWM MATLAB simulation program, hope that those interested in mutual exchange )

计算中间接轴在正弦激励下的动态特性，最大剪切应力、最大等效应力、弯曲应力等。(Axis in the calculation of indirect dynamic characteristics under sinusoidal excitation, the maximum shear stress, the maximum equivalent stress, bending stress and so on.)

Sines. Sum sines. Every operations with sines and cosines.

另一个matlab版本的差分进化算法，跟前面上传的有差别。(A differential evolutionary algorithm coded by matlab)

可实现函数的产生，基本运算，时域频域分析(Generation function, basic operations, time domain frequency domain analysis)
