[Octave-bug-tracker] [bug #65089] assert may become excessively slow in case of large matrices

[anonymous]

Follow-up Comment #7, bug#65089 (group octave):

What I was thinking about is something like this:

assert_msg_limit=1000;
tol = eps;
N = 1000;
a = rand(N, N);
b = rand(N, N);
tic; 
cond_fail=(abs(a - b) > tol); 
n_fail=sum(cond_fail(:));
toc;
if (n_fail > assert_msg_limit)
  error("assert failed: %d values are out of tolerance; max difference is %g >
%g; message is too long ...", n_fail, max(abs(a - b)(:)), tol);
endif
