Standard-deviation-and-mean

粒子群寻优。 利用粒子群寻优的方法，对神经网络进行训练。该源程序对以前的程序进行了改进。(Particle swarm optimization. The use of particle swarm optimization method for neural network training. The source of the previous procedure has been improved.)

BILATERAL FILTER GUI

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. )

The code can create a model by calling the WEKA tool in matlab. The input file should be in .arff format
