Function File: semimajoraxis = majaxis (semiminoraxis, ecc) ¶

Return the semimajor axis given the semiminoraxis (b) and eccentricity (e).

Examples

Scalar input:

 earth_b = 6356752.314245;  ## meter
 earth_ecc = 0.081819221456;
 a = majaxis (earth_b, earth_ecc)
 => a =
  6.3781e+06

Vector input:

 planets_b = [ 6356752.314245 ; 66854000 ]; ## meter
 planets_ecc = [ 0.081819221456 ; 0.3543164 ];
 planets_a = majaxis ( planets_b , planets_ecc )
 => planets_a =
     6.3781e+06
     7.1492e+07
