re:RE: st: passing a function name as an argument to another function

[Christopher Baum <kit.baum@bc.edu>]

This will definitely work but it means that I'm calling stata routine from mata (my caller procedure is in mata) that does nothing other that passing arguments back to a mata function...not the most beautiful solution I guess but whatever works :)


No need--can be done entirely within Mata. See {m-2] ftof.

clear all
mata:
real function x2(real scalar x) 
{
	return(x^2)
}

void function test(
	pointer(real scalar function) scalar f,
	real scalar x)
{
	xx = (*f)(x)
	xx
}

test(&x2(), 4)

end
