Details:
"make check" on the default branch gives ....
***** assert ( quadl (@(x) sin (2 + 3*x).^2, 0, 10, 0.3, []),
(60 + sin(4) - sin(64))/12, -0.3)
!!!!! test failed
assert (quadl (@(x) sin (2 + 3 * x) .^ 2, 0, 10, 0.3, []),(60 + sin (4) - sin
(64)) / 12,-0.3) expected
4.8603
but got
8.1963
maximum relative error 0.686392 exceeds tolerance 0.3
I get the same result with the stable branch (although the test does not part
of quadl)
Matlab passes, so I assume the test is correct, but there is some problem with
quadl.
>> [quadl(@(x) sin (2 + 3*x).^2, 0, 10, 0.3, []),
(60 + sin(4) - sin(64))/12]
ans =
4.859710511212103
4.860264288874607
