Describes the routines FIEINI (parses an input string
which contains mathematical expression), FIEDO (which
does the actual calculations) and FIEDUMP (which dumps
the code generated by FIEINI).

INVMAT is a routine for inverting a matrix. The algorithm used
is the Gauss-Jordan algorithm described in Stoer, Numerische
Matematik, 1 Teil.

LSQFIT is a routine for making a least-squares fit of a
function to a set of data points. The method used is
described in: Marquardt, J.Soc.Ind.Appl.Math. 11, 431 (1963).
This method is a mixture of the steepest descent method and
the Taylor method.

LSQFITD is a routine for making a least-squares fit of a
function to a set of data points. The method used is
described in: Marquardt, J.Soc.Ind.Appl.Math. 11, 431 (1963).
This method is a mixture of the steepest descent method and
the Taylor method.

SKYFIT is a routine for determining the sky-projection
parameters. It takes a set of grid positions and a set
of sky coordinates to fit the parameters.
The method is a mixture of the steepest descent method and
the Taylor method.
