NSEDFEllipsoid是基于NESEDF椭圆拟合方法改进的椭球拟合方法。
函数alpha = NSEDFEllipsoid(X,Y,Z)根据椭球代数距离公式a(1)x^2 + a(2)y^2 + a(3)z^2 + a(4)xy + a(5)xz + a(6)yz + a(7)x + a(8)y + a(9)z + a(10) = 0拟合得到椭球方程的10个系数，其中X、Y、Z是采样点坐标的列向量集合。

Function alpha = NSEDFEllipsoid(X,Y,Z) gives the 10 parameter vector of the algebraic ellisoid fit to a(1)x^2+ a(2)y^2+ a(3)z^2+ a(4)xy+ a(5)xz+ a(6)yz+ a(7)x+ a(8)y+ a(9)z+ a(10) = 0， where X & Y & Z are lists of point coordinates and must be column vectors.
