实现两个稀疏矩阵相乘(效率高于早期的Matlab自带的程序)，Matlab编程 (SSMULT is a simple stand-alone MATLAB mexFunction that computes C=A*B where both A and B are sparse. It is typically faster and always uses less memory than C=A*B in MATLAB 7.4 (or earlier). Works on MATLAB 6.1 to the current version. Untested on earlier versions of MATLAB. It is a built-in function in MATLAB 7.6 and later for C=A*B when both A and B are sparse. )

This is the code for finding the contour of object on the basis of distance regularized basis.

用matlab编制卫星运动的动画程序，非常有趣！(A cartoon programme of star moving using matlab code)

说明：  利用FFT对原信号进行变换，然后在频域进行处理，再使用IFFT进行反变换，达到滤波的目的。(use FFT and IFFT to filter)

通过步进频率技术进行带宽合成，通过脉冲压缩，验证先压缩与后压缩的区别。结果表演，压缩后拼接与拼接后压缩效果一致。(Through the step frequency technology for the synthesis of bandwidth, through the pulse compression, verify the compression sequence don t affect the result of bandwidth synthesis.)
