Hi everybody!
I tried to make a .oct-file from a fortran-file, but had no success.
I get "error: `iau_SP00' undefined near line 2 column 1" when calling the
function.
* I started with the subroutine sp00.for from SOFA
(http://www.iau-sofa.rl.ac.uk/2008_0301/Downloads.html).
* I replaced all special Characters in sp00.for (\r\n to \n and such) and
renamed it to sp00.f (checked with vim)
* called from bash mkoctfile -o iau_SP00.oct sp00.f. This executed without
an error and returned the iau_SP00.oct-file
* started octave from bash
* added the path whit the .oct-file
* tried to run it with and without parameters and always get the same error
(as above).
Thanks for any help!
Here is the sp00.for code:
DOUBLE PRECISION FUNCTION iau_SP00 ( DATE1, DATE2 )
*+
* - - - - - - - - -
* i a u _ S P 0 0
* - - - - - - - - -
*
* The quantity s', positioning the Terrestrial Ephemeris Origin on the
* equator of the Celestial Intermediate Pole.
*
* This routine is part of the International Astronomical Union's
* SOFA (Standards of Fundamental Astronomy) software collection.
*
* Status: canonical model.
*
* Given:
* DATE1,DATE2 d TT as a 2-part Julian Date (Note 1)
*
* Returned:
* iau_SP00 d the quantity s' in radians (Note 2)
*
* Notes:
*
* 1) The TT date DATE1+DATE2 is a Julian Date, apportioned in any
* convenient way between the two arguments. For example,
* JD(TT)=2450123.7 could be expressed in any of these ways,
* among others:
*
* DATE1 DATE2
*
* 2450123.7D0 0D0 (JD method)
* 2451545D0 -1421.3D0 (J2000 method)
* 2400000.5D0 50123.2D0 (MJD method)
* 2450123.5D0 0.2D0 (date & time method)
*
* The JD method is the most natural and convenient to use in
* cases where the loss of several decimal digits of resolution
* is acceptable. The J2000 method is best matched to the way
* the argument is handled internally and will deliver the
* optimum resolution. The MJD method and the date & time methods
* are both good compromises between resolution and convenience.
*
* 2) The quantity s' is obtained from polar motion observations by
* numerical integration, and so is in essence unpredictable.
* However, it is dominated by a secular drift of about
* 47 microarcseconds per century, which is the approximation
* evaluated by the present routine.
