Parameters

xmin

double

Lower bound for root search.

xmax

double

Upper bound for root search.

function

Func<double, double>

The function to evaluate.

res

double

The x value for the root.

tol

double

The iteration stops when this tolerance is reached. If never reached it stops after 1000 iterations.

zerotol

double

If abs(funtion(xmin or xmax)) xmin/xmax is smaller than this value and same signs for xmin/xmax is sent, it is reported as success. This is to find roots close to 0 but with a small tolerance error. Set to negative to disable.

Return Value
