| Function | retrieve the current significance threshold for data fitting to linear models |
|
| Syntax C/C++ | #include <MFstd.h>
float VF_getLinfitNeglect( void ); |
| C++ MatObj | #include <OptiVec.h>
T vector<T>::getLinfitNeglect();
T matrix<T>::getLinfitNeglect(); |
| Pascal/Delphi | uses MFstd;
function VF_getLinfitNeglect:Single; |
|
| Description | Internally, the linear-fitting functions like VF_linfit employ a Singular Value Decomposition algorithm to obtain a solution even for (near-)singular linear systems. Thereby, coefficients ai whose significance is lower than a threshold, Thresh, are set to 0 instead of infinity. This threshold can be modified by calling VF_setLinfitNeglect. The current threshold can be retrieved by VF_getLinfitNeglect.
In the C++ MatObj version, this function takes only the data type from the matrix as whose member function it is called, but has nothing specific to do with it otherwise. |

| Return value | current significance threshold for linear fitting |
