Function Documentation

romberg()

std::string steppable::__internals::calculus::romberg	(	const std::function< std::string(std::string)> &	f,
		const std::string &	a,
		const std::string &	b,
		int	max_steps,
		int	decimals )

Calculates the Romberg integration of f.

Parameters

f	The function to integrate. It takes in one argument and returns a string.
a	Lower bound of integral.
b	Upper bound of integral.
max_steps	Maximum steps of integral. More steps can produce higher accuracy, but takes a longer time.
decimals	The decimals to output.

Returns

The result of the integral.

Note

The function must take in exactly ONE argument, in the form of std::string. The output must be a std::string object. Wrap your function in a lambda expression if it takes more arguments, or outputs in a different type.
