ncl_c_ftcurv(3) - Linux man page

Name

c_ftcurv - 1D interpolation for non-periodic functions

Function Prototype

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

Synopsis

int c_ftcurv (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 interpolated values.
xo: An array containing the abscissae for the interpolated values.
yo: An array containing the interpolated functional values -- yo(k) is the functional value at xo(k) for k=0,n.

Return Value

c_ftcurv 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_ftcurv 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_ftcurv are: sig, sl1, sln, sf1.

Access

To use c_ftcurv, load the NCAR Graphics library ngmath.
