用matlab软件编写感知器算法，实现对样本的分类，样本点为X1(0，0)，X2(0，-1)，X3(-1，0)，X4(-1，-1)

　　X1,X2属于第一类，X3、X4属于第二类；（编程）

　　X1、X4属于第一类，X2，X3属于第二类；（计算）-Perceptron Algorithm matlab software, to achieve the classification of samples, sample points X1 (0,0), X2 (0,-1), X3 (-1,0), X4 (-1,-1)　X1 belonging to the first category, X2, X3, X4 belongs to the second category　(programming) X1 and X4 belongs to the first class, X2, X3 belonging to the second category　(computing)
