parse()

template<typename real_t, typename Iterator>

detail::expr_ast< real_t > matheval::detail::parse	(	Iterator	first,
		Iterator	last )

Parse an expression.

This function builds the grammar and parses the iterator into an AST.

Parameters

[in]	first	iterator to the start of the input sequence
[in]	last	iterator to the end of the input sequence
