如上程序运行过程中，总是报错：
double
Attempt to call constructor double with incorrect letter case.
Error in linspace (line 20)
n = double(n);
Error in D:matlab oolboxmatlabgraph2dplotyy.p>plotyy (line 137)
Error in double (line 4)
[AX,H1,H2] = plotyy(x,y1,x,y2,'plot');
运行报错,但是出波形,如下:但是没有对坐标轴的标注以及图例的标注

难道是电脑的问题吗？我安装了好几个版本的matlab，都不行
