ellipse_coeffs(a, b, theta)¶
Convert from ellipse axes and angle to coefficient representation.
- a, b, theta : array_like
Ellipse(s) semi-major, semi-minor axes and position angle respectively. Position angle is radians counter clockwise from positive x axis to major axis, and lies in range
- cxx, cyy, cxy :
Describes the ellipse(s)
cxx * x^2 + cyy * y^2 + cxy * xy = 1
