Static members

Static member	Description
`QuickRootFinding.BracketRootByExtensionOnly(func, ysearch, x0, x1)` Full Usage: `QuickRootFinding.BracketRootByExtensionOnly(func, ysearch, x0, x1)` Parameters: func : `Func<float, float>` - The function used to evaluate the function values. ysearch : `float` - The value to find. x0 : `byref<float>` - Starting parameter of x0, at the end the lower value of the bracket interval. x1 : `byref<float>` - Starting parameter of x1, at the end the upper value of the bracket interval. Returns: `bool` True if a bracket interval was found. If such an interval could not be found, the return value is false.	Find the bracket of a root, i.e. values for x0 and x1, so that ysearch is inbetween f(x0) and f(x1). This is done be extension of the interval [x0,x1] either to the left or the right side or both. func : `Func<float, float>` The function used to evaluate the function values. ysearch : `float` The value to find. x0 : `byref<float>` Starting parameter of x0, at the end the lower value of the bracket interval. x1 : `byref<float>` Starting parameter of x1, at the end the upper value of the bracket interval. Returns: `bool` True if a bracket interval was found. If such an interval could not be found, the return value is false.
`QuickRootFinding.ByBrentsAlgorithm(f, x0, x1)` Full Usage: `QuickRootFinding.ByBrentsAlgorithm(f, x0, x1)` Parameters: f : `Func<float, float>` x0 : `float` x1 : `float` Returns: `float`	f : `Func<float, float>` x0 : `float` x1 : `float` Returns: `float`
`QuickRootFinding.ByBrentsAlgorithm(f, x0, x1, epsabs, epsrel)` Full Usage: `QuickRootFinding.ByBrentsAlgorithm(f, x0, x1, epsabs, epsrel)` Parameters: f : `Func<float, float>` x0 : `float` x1 : `float` epsabs : `float` epsrel : `float` Returns: `float`	f : `Func<float, float>` x0 : `float` x1 : `float` epsabs : `float` epsrel : `float` Returns: `float`
`QuickRootFinding.ByBrentsAlgorithm(f, x0, x1, epsabs, epsrel, root)` Full Usage: `QuickRootFinding.ByBrentsAlgorithm(f, x0, x1, epsabs, epsrel, root)` Parameters: f : `Func<float, float>` x0 : `float` x1 : `float` epsabs : `float` epsrel : `float` root : `byref<float>` Returns: `GSL_ERROR`	f : `Func<float, float>` x0 : `float` x1 : `float` epsabs : `float` epsrel : `float` root : `byref<float>` Returns: `GSL_ERROR`
