Syntax public LinearFitBySvd(
double[] xarr,
double[] yarr,
double[]? stddev,
int numberOfData,
int numberOfParameter,
FunctionBaseEvaluator evaluateFunctionBase,
double threshold
)
Parameters
- xarr Double
- The array of x values of the data set.
- yarr Double
- The array of y values of the data set.
- stddev Double
- The array of y standard deviations of the data set. Can be null if the standard deviation is unkown.
- numberOfData Int32
- The number of data points (may be smaller than the array sizes of the data arrays).
- numberOfParameter Int32
- The number of parameters to fit == size of the function base.
- evaluateFunctionBase FunctionBaseEvaluator
- The function base used to fit.
- threshold Double
- A treshold value (usually 1E-5) used to chop the unimportant singular values away.
