## Speed of Octave vs. Matlab

 From: Justin Donnelly Summer Student Subject: Speed of Octave vs. Matlab Date: Fri, 23 Aug 1996 13:38:21 -0700

```I just ran the first two tests in Matlab 4.2's bench.m program on both
Octave and Matlab, and it took about 15 times as long on Octave.  Is Octave
really this slow?  Or is there some common problem which might be the cause
of this difference?

Here is the code that I'm running:

------------------------------------------
function [t] = mybench(count)

if nargin < 1, count = 10; end;

if count > 0
t = 0;

% Loops
n = 375;
A = [];
r = 1;
tic
for k = 1:count
for j = 1:n
clear A;
r = rem(pi*r,1);
m = fix(100*r);
A = zeros(m,m);
end
end
t(1) = toc;

% LU
n = 167;
A = rand(n,n);
tic
for k = 1:count
lu(A);
end
t(2) = toc;

end
---------------------------------------

Thanks,
Justin
