Follow-up Comment #3, bug #58636 (project octave):
need to see if there's a way to catch complex functions. something link
integral (exp (i*x), 0, 1) evaluates to real values at the real endpoints, so
it'll sneak past the check. Also, not sure about whether there are other
not-so-obvious complex functions. even something like
>> fx = @(x) complex(x)
fx =
@(x) complex (x)
>> quadgk(fx,0,1)
ans = 0.50000
>> quadcc(fx,0,1)
error: quadcc: integrand F must return a single, real-valued vector
needs to be caught.
