Description Usage Arguments Details Value Author(s) Examples

this routine discretizes a value corresponding to the desired method

1	discretize_cpp(val, N_discr, domain, method)

`val`	double - real value to be discretized
`N_discr`	integer - desired discretization
`domain`	vector of double - vector with two components containing the domain bounds
`method`	integer - discretize with 1...round routine, or 2...custom method

This routine is implemented in C++

double - discretized value
