Syntaxpublic static double Evaluate(
double x,
double xc,
double y0,
ReadOnlySpan<double> coeffs_left,
ReadOnlySpan<double> coeffs_right
)
Parameters
- x Double
- The x value.
- xc Double
- The xc value which is the x-value of the transition between the two segments.
- y0 Double
- The y0 value of the transition. This is the y-value of the curve at xc if the transition is sharp (sigma == 0).
- coeffs_left ReadOnlySpanDouble
- The polynomial coefficients of the left polynomial (order 1, order 2, ...).
- coeffs_right ReadOnlySpanDouble
- The polynomial coefficients of the right polynomial (order1, order 2, ...).
Return Value
DoubleThe y value of the function at x.
