Briefly browse the table of contents to
get a general
feel for what is in the Fitgrid package.
Fitgrid can be accessed by using any one of three interfaces: Fortran, C, and
NCL.
This interface is identical to the original Fitpack interface.
Examine the procedures overview module for
a summary of the Fortran entries. From there you can click on the
desired procedure name for details on how to call it correctly.
Also, see the examples section for learning how
to use the Fortran interface.
This interface has been added to the original Fitpack package. The C
interface differs from the Fortran interface in that many of the arguments
to the original procedures have been converted into user-settable
global parameters. The idea is to set values for the
appropriate parameters and then invoke the desired procedure.
For a list of all parameters, see the
parameters module. The default values
for the parameters are listed there.
The functions
c_ftseti,
c_ftsetr,
c_ftsetc,
c_ftsetfa are used
for setting parameter values.
Examine the procedures overview module for
a summary of the C entries. From there you can click on the
desired function name for details on how to call it correctly.
The documentation for each C function indicates which parameters
are appropriate for that function.
Also, see the examples section for learning how
to use the C interface.
The NCL interface is much simpler than the
Fortran or C interfaces. The basic way to proceed is the same as for
the C interface: set values for global parameters and invoke the
desired NCL function or procedure. The parameters are listed in
the parameters module.
Examine the
NCL Fitgrid
documentation to learn how to use the NCL interface. Note that there is
only a single procedure needed for setting values for the parameters.
Also, see the examples section for learning how
to use the NCL interface.
