fisher线性分类器算法，算法实现三维空间中样本中各点的分类情况。-fisher linear classifier algorithm to achieve three-dimensional sample points in the classification.

用fisher分类器实现简单的分类，首先进行样本的训练，然后对待测样本进行测试，程序中画出了分界面。-Fisher classifier with a simple classification, first of all to the training sample, then treatment of test samples for testing, the interface of the program are drawn.
