Calculate semiminor axis from semimajor axis and eccentricity
Syntax
semiminor = minaxis(semimajor,eccentricity) semiminor = minaxis([semimajor,eccentricity])
Description
The semiminor axis can be determined given both the semimajor axis and the eccentricity, the two elements of standard geoid vector in the Mapping Toolbox. semiminor = minaxis(semimajor,eccentricity) returns the semiminor axis length corresponding to the input semimajor axis and eccentricity. semiminor = minaxis([semimajor,eccentricity]) allows the inputs to be packed into a single, two-column input of the form [semimajor, eccentricity].Examples
Using the default values for the Earth:semiminor = minaxis(almanac('earth','geoid'))
semiminor =
