Follow-up Comment #29:

Just a note:
your aer2ecef.m gives slightly different results than Matlab.

Octave aer2ecef:

>> [x2, y2, z2] = aer2ecef (33, 70, 1e3, 42, -82, 200, 'wgs84')
x2 = 6.6063e+05
y2 = -4.7007e+06
z2 = 4.2448e+06
>> [x, y, z] = aer2ecef (pi/6, pi/3, 1e3, pi/4, -pi/2, 200, 'wgs84', 'rad')
x = 250.00
y = -4.5180e+06
z = 4.4884e+06


where Matlab needs the actual spheroid (not the name) and then yields:

>> wgs84 = wgs84Ellipsoid('meters');
>> [x, y, z] = aer2ecef (33, 70, 1e3, 42, -82, 200, wgs84)
x =
   6.6093e+05
y =
  -4.7014e+06
z =
   4.2466e+06
>> [x, y, z] = aer2ecef (pi/6, pi/3, 1e3, pi/4, -pi/2, 200, wgs84, 'rad')
x =
  250.0000
y =
  -4.5180e+06
z =
   4.4884e+06
