Method Detail

integrate

public double integrate(ComputableFunction f,
                        double a,
                        double b)
                 throws FunctionException

Integrate a function over a defined range.

Parameters:

f - function to integrate

a - first bound of the range (can be lesser or greater than b)

b - second bound of the range (can be lesser or greater than a)

Returns:

value of the integral over the range

Throws:

FunctionException - if the underlying function throws one
