Data Fitting Computational Routines
Data Fitting computational routines are functions used to perform spline-based computations, such as:
spline construction
computation of values, derivatives, and integrals of the predefined order
cell search
Once you create a Data Fitting task and initialize the required parameters, you can call computational routines as many times as necessary.
The table below lists the available computational routines:
Routine |
Description |
---|---|
Constructs a spline for a one-dimensional Data Fitting task. |
|
Computes spline values and derivatives. |
|
Computes spline values and derivatives by calling user-provided interpolants. |
|
Computes spline-based integrals. |
|
Computes spline-based integrals by calling user-provided integrators. |
|
Finds indices of cells containing interpolation sites. |
|
Finds indices of cells containing interpolation sites by calling user-provided cell searchers. |
If a Data Fitting computation completes successfully, the computational routines return the DF_STATUS_OK code. If an error occurs, the routines return an error code specifying the origin of the failure. Some possible errors are the following:
- The task pointer is NULL.
- Memory allocation failed.
- The computation failed for another reason.
For the list of available status codes, see "Task Status and Error Reporting".
Data Fitting computational routines do not control errors for floating-point conditions, such as overflow, gradual underflow, or operations with Not a Number (NaN) values.
