matlab中极坐标函数的改进，坐标轴刻度可以为负数，输入参数见注释，有问题email联系，可在matlab命令行中直接运行，如：
my_polar2([0,20,30]*pi/180,[-10,0,10], -r ,-20,30)-Matlab polar coordinates function improved, axes calibration can be negative, the input parameters, see Notes email problems can be contacted in Matlab command line direct operations, such as : my_polar2 ([0,20,30]* pi/180 [-10,0,10],- r,-20,30)
