Parameters

func

NumericFunctionDelegate

The function whose roots are to be found.

root

double[]

An array that will contain the roots found. Each entry of this array that contains another number than 0.0 is seen as an initial guess for the solution. The length of this array decides the maximum number of roots found.

userdata

object

Any data sent back to the callback function.

maxiter

long

Maximum number of iterations. Don't choose this number to large if speed is crucial.

epsr

double

Relative convergence criterion on successive iterations.

epsf

double

Absolute convergence criterion on the function values.

epsmr

double

Closeness of multiple roots (see mrspr).

mrspr

double

The spread for multiple roots, that is, if |rt - root[i]| is less tan epsmr, where root[i] is a previously found root, then rt is replaced by rt + mrspr.

Return Value

The number of roots found.
