中文说明：包括随机梯度算法，相对梯度算法，基于分段非线性权重值的Pso算法，正确率可以达到98％，包括面积、周长、矩形度、伸长度，利用matlab GUI实现的串口编程例子，真的是一个好程序。
English Description：
Includes stochastic gradient algorithm, algorithm of relative gradient, Pso algorithm based on piecewise linear weights, with an accuracy rate can reach 98%, including area, perimeter, rectangular, elongation, serial programming using MATLAB GUI example really is a good program.
