Semiminor axis of ellipse
b = minaxis(semimajor,e)
b = minaxis(vec)
b = minaxis(semimajor,e) computes the semiminor axis of an ellipse (or ellipsoid of revolution) given the semimajor axis and eccentricity. The input data can be scalar or matrices of equal dimensions.
b = minaxis(vec) assumes a 2 element vector (vec) is supplied, where vec = [semimajor, e].
