代码如下
ListPolarPlot[{{0, 0.811}, {20 Pi/180, 0.759}, {40 Pi/180,
0.621}, {60 Pi/180, 0.521}, {80 Pi/180, 0.469}, {90 Pi/180,
0.456}, {100 Pi/180, 0.457}, {120 Pi/180, 0.487}, {140 Pi/180,
0.566}, {160 Pi/180, 0.706}, {Pi, 0.833}, {200 Pi/180,
0.778}, {220 Pi/180, 0.632}, {240 Pi/180, 0.518}, {260 Pi/180,
0.464}, {270 Pi/180, 0.457}, {280 Pi/180, 0.456}, {300 Pi/180,
0.487}, {320 Pi/180, 0.567}, {340 Pi/180, 0.700}, {360 Pi/180,
0.811}}, Joined -> True]
想问下怎么拟合成一个椭圆而不是单纯是点的连线
