Parameters
- targetFunction
- Type: SystemFuncDouble, Double
A delegate that represents a function of one variable that specifies the function on the left-hand
side of the equation. - derivativeOfTargetFunction
- Type: SystemFuncDouble, Double
A delegate that represents a function of one variable that specifies the derivative
function of targetFunction. - initialGuess
- Type: SystemDouble
An initial guess for ther zero.
Return Value
Type:
EquationSolverThe best approximation to a zero of
targetFunction.
Use this method when you have very little information about the location of the zero, but you need more control
over the solution process. For example, you may want to specify a different RelativeTolerance.
