通过自动阈值选择方法实现图像二值化。初始阈值T是图像均值；T把图像直方图分成R1和R2两个区域；计算R1和R2均值u1和u2，选择u1和u2均值作新的阈值；重复以上步骤直到T值基本不变。(Automatic Threshold Selection；)

包括手写文字识别的各个步骤，图像的预处理、裁剪、大小转换、人工神经网络训练和识别等等。(Handwritten character recognition, including the various steps, image preprocessing, cropping, size, conversion, training and recognition of artificial neural networks and so on.)

this code is about Generalize Side Lobe Canceller and very important in array processing.

单纯形法matlab程序 求解标准型线性规划:max c*x s.t. A*x=b x>=0 本函数中的A是单纯初始表，包括:最后一行是初始的检验数，最后一列是资源向量b N是初始的基变量的下标 输出变量sol是最优解, 其中松弛变量（或剩余变量）可能不为0 输出变量val是最优目标值，kk是迭代次数( example：max 2*x1+3*x2 s.t. x1+2*x2<=8 4*x1<=16 4*x2<=12 x1,x2>=0)
