NAME

       c_ftcurvd - calculate derivatives

FUNCTION PROTOTYPE

       int c_ftcurvd (int, float [], float [], int, float [], float []);

SYNOPSIS

       int c_ftcurvd (n, xi, yi, m, xo, yo);

DESCRIPTION

       n           The number of input data points. (n > 1)

       xi          An array containing the abscissae for the input function.

       yi          An array containing the functional values of the input function -- y(k) is the
                   functional value at x(k) for k=0,n.

       m           The number of desired derivatives.

       xo          An array containing the abscissae for the output values.

       yo          An array containing  the  interpolated  derivative  values  --  yo(k)  is  the
                   functional derivative at xo(k) for k=0,n.

RETURN VALUE

       c_ftcurvd returns an error value as per:

       = 0 -- no error.
       = 1 -- if n is less than 2.
       = 2 -- if X values are not strictly increasing.

USAGE

       c_ftcurvd  is  called after all of the desired values for control parameters have been set
       using the procedures c_ftseti, c_ftsetr,  c_ftsetc.   Control  parameters  that  apply  to
       c_ftcurvd are: sig, sl1, sln, sf1.

ACCESS

       To use c_ftcurvd, load the NCAR Graphics library ngmath.
