怎么用matlab拟合极坐标曲线
物理实验数据处理作图 现代码如下：
theta2=linspace(0,2*pi*35/36,36);
i1=[192,185.5,173,149.9,109,87,50,30.9,10.2,4.9,10.4,26];
i2=[58,85.5,118.5,151.6,161.5,159.2,192.3,159.1,161.6,124.1,111.4,74];
i3=[47.7,28.3,10.7,5.2,10.4,29.1,51.9,82.3,112.5,138.6,174.3,182];
i=[i1 i2 i3];
polar(theta2,i);
但是图形效果太差了……求大牛指教

theta2=linspace(0,2*pi,37);
i1=[192,185.5,173,149.9,109,87,50,30.9,10.2,4.9,10.4,26];
i2=[58,85.5,118.5,151.6,161.5,159.2,192.3,159.1,161.6,124.1,111.4,74];

i=[i1 i2 i3 i1(1)];
polar(theta2,i);
如果这个不行,可以手动设线宽,增加取点试试看
