小圆与椭圆

定义小圆与椭圆

小圆是平面与球面相交形成的截面。椭圆是平面与圆锥曲面的交线。使用这些函数生成椭圆与小圆的坐标，并求解小圆的交点。

函数

aoicircle Define circular area of interest (自 R2024b 起)

`ellipse1`	Geographic ellipse from center, semimajor axis, eccentricity, and azimuth
`scircle1`	Small circle from center and radius
`scircle2`	Small circle from center and point on perimeter
`gc2sc`	Center and radius of great circle
`scircleg`	Add small circle to `axesm`-based map using mouse

`gcxsc`	大圆与小圆对的交点
`scxsc`	Intersection points for pairs of small circles
