问题描述
我有一个theta
和phi
值的数组.如何轻松创建theta
和phi
是这样的球面坐标的MATLAB图:
I have an array of values for theta
and phi
. How can I easily create a MATLAB plot where theta
and phi
are spherical coordinates like this:
如果我有一个theta
和phi
的数组且半径保持不变,如何在MATLAB中绘制值?
How to plot the values in MATLAB if I have an array of the theta
and phi
with radius kept constant?
这些是theta
的值:
theta = [ 80.0000 73.2995 65.7601 95.5007 100.4861 97.8834 94.0849 52.5174 74.4710 104.6674 52.7177 97.0538 75.7018 83.2817 97.5423 85.1797 84.2677 126.2296 81.1814 66.1376 91.6953 167.7085 46.5980 87.8220 113.4588 180.0000 80.7624 95.8623 115.0538 76.5773 61.9858 141.0402 109.9872 76.1273 84.4166 75.2734 110.4489 82.2434 96.8303 100.0815 73.2454 82.0755 64.6457 76.3510 87.7863 133.2706 86.1305 76.8670 86.3225 96.8016 49.2653 107.2900 145.9905 59.2158 107.7546 180.0000 93.9687 87.5474 103.1400 180.0000 136.8251 180.0000 106.2629 109.0069 ];
phi
的值是:
phi = [ -90.0000 -78.5230 -51.6764 84.6854 58.1182 -75.9705 78.0541 -60.0560 88.8935 -84.6539 -44.1415 -86.7643 61.7764 -87.4767 -86.9440 -80.2459 -76.8752 88.9510 64.7297 -51.1245 -83.1606 -88.7280 -32.7110 81.0951 86.8393 -0.0000 52.6243 -88.7833 -75.4600 84.1374 79.8300 -86.7258 -65.8055 80.9829 -89.3172 57.1802 -80.6346 72.5277 -87.4452 74.2778 -86.1069 76.6124 -80.4604 89.2202 85.0649 89.2164 -79.0290 84.9961 -88.2301 -87.5064 50.4016 83.0830 82.4863 -50.8481 87.0335 -0.0000 88.4613 79.7583 -80.6474 -0.0000 80.0771 -0.0000 89.2428 -82.769 ];
所需的绘图应在图形上与此相似:
The desired plot should be pictorially similar to this:
我尝试使用plot(ptheta)
,我得到了:
I tried using plot(ptheta)
and I got this:
在按安德拉斯(Andras)建议绘制后
after plotting as suggested by andras
推荐答案
您可以尝试以下方法吗:
Can you try this:
[X, Y, Z] = sph2cart(theta, phi, P);
plot3(X, Y, Z)
然后使用[旋转3D]按钮将其旋转以使其外观更好.
Then use [Rotate 3D] button to rotate it to better looking.
