Library information functions

IRBEM_FORTRAN_VERSION

Provides the repository version number of the fortran source code.

Outputs:

• VERSN (integer) – IRBEM version number

Calling sequence:

From MATLAB

VERSN = onera_desp_lib_fortran_version

From IDL

result = call_external(lib_name, 'irbem_fortran_version',versn, /f_value)

From FORTRAN

call IRBEM_FORTRAN_VERSION1(VERSN)

IRBEM_FORTRAN_RELEASE

Provides the repository release tag of the fortran source code.

Outputs:

• RLS (array of 80 characters) – release tag

Calling sequence:

From MATLAB

RLS = onera_desp_lib_fortran_release

From IDL

result = call_external(lib_name, 'irbem_fortran_release', rls, /f_value)

From FORTRAN

call IRBEM_FORTRAN_RELEASE1(RLS)

Note:

In IDL, string arguments should be defined as byte arrays, i.e.: rls = BYTARR(80)

GET_IGRF_VERSION

Returns the version number of the IGRF model.

Outputs:

• IGRF_VERSION (integer) – IGRF version number

Calling sequence:

From MATLAB

igrf_version = onera_desp_lib_igrf_version

From IDL

result = call_external(lib_name, 'igrf_version_idl',igrf_version, /f_value)

From FORTRAN

call GET_IGRF_VERION_(igrf_version)

GET_IRBEM_NTIME_MAX

Returns the size of time dimension in inputs and/or output arrays for some of the routines.

Note

In previous versions, the ntime_max parameter was used extensively in the IRBEM library.

When possible (which is when the time dimension is the first dimension of the array), the IRBEM routines now use variable-length array, so arbitrary array length can be provided, as long as the array is big enough to contain the needed data (usually of size ntime).

For routines where the ntime_max array size is still needed, it is explicitely mentioned in the corresponding part of this documentation.

Outputs:

• NTIME_MAX (integer) – Time dimension size

Calling sequence:

From MATLAB

ntime_max = onera_desp_lib_ntime_max

From IDL

result = call_external(lib_name, 'get_irbem_ntime_max',ntime_max, /f_value)

From FORTRAN

call GET_IRBEM_NTIME_MAX1(ntime_max)
