Details:
The first unit test in file bim1c_norm.m fails randomly. This is the recipe
for triggering the bug:
octave:1> pkg load bim
octave:2> while 1
L = rand (1); V = rand (1); m = linspace (0,1,5).^2; m *= L;
u = V * ones (size (m))';
uinf = bim1c_norm (m, u, 'inf');
uL2 = bim1c_norm (m, u, 'L2');
uH1 = bim1c_norm (m, u, 'H1');
assert ([uinf, uL2, uH1], [V, V*sqrt(L), V*sqrt(L)], 1e-12);
endwhile
error: ASSERT errors for: assert ([uinf, uL2, uH1],[V, V * sqrt(L), V *
sqrt(L)],1e-12)
Location | Observed | Expected | Reason
(3) 0.051682 0.051682 Abs err 4.7937e-12 exceeds tol 1e-12
by 4e-12
The patch attached to this bug report fixes the problem.
