df?construct1d

Constructs a spline of the given type.

Syntax

FORTRAN:

status = dfsconstruct1d(task, s_format, method)

status = dfdconstruct1d(task, s_format, method)

status = dfsConstruct1D(task, s_format, method)

status = dfdConstruct1D(task, s_format, method)

Description

Before calling df?construct1d, you need to create and initialize the task, and set the parameters representing the spline. Then you can call the df?construct1d routine to construct the spline. The format of the spline is defined by parameter s_format. The method for spline construction is defined by parameter method. Upon successful construction, the spline coefficients are available in the user-provided memory location in the format you set through the Data Fitting editor. For the available storage formats, see table "Hint Values for Spline Coefficients".
