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. )
