The purpose of which is the efficient support of sparse matrices in Octave. This task is a bit tasking on me. I recently took a took at Octave's patch and was quickly lost.

[Fink-users] trouble with Octave
I have both PPC and Intel installations of Octave. They both give the wrong answer to this short script. num = [1 0 1]; den = [1 0 18 0 81]; [a,p,k,e] = residue(num,den) I did the math ... (x^2+1)/(x^4+18*x^2+81) = (2/9)/(x-3i) + (2/9)/(x+3i) + (1/54i)/(x-3i)^2 - (1/54i)/(x+3i)^2 Thus, a = [1/54i 2/9 -1/54i 2/9] p = [3i 3i -3i -3i] k = [] e = [2 1 2 1] However, my Intel version gives a = -3.0108e+06 - 1.9734e+06i -3.0108e+06 + 1.9734e+06i 3.0108e+06 + 1.9734e+06i 3.0108e+06 - 1.9734e+06i p = -0. + 3.i -0. - 3.i 0. + 3.i 0. - 3.i k = [](0x0) e = 1 1 1 1 and my PPC version gives a = 8.4492e+06 - 3.9658e+06i 8.4492e+06 + 3.9658e+06i -8.4492e+06 + 3.9658e+06i -8.4492e+06 - 3.9658e+06i p = 0. + 3.i 0. - 3.i -0. + 3.i -0. - 3.i k = [](0x0) e = 1 1 1 1 For reference, Matlab gives a = 0 - 0.0926i 0. - 0.i 0 + 0.0926i 0. + 0.i p = 0. + 3.i 0. + 3.i 0. - 3.i 0. - 3.i k = [] A non-Fink installation for 2.9.14 produces the correct answer as well, see the link below. http://www.nabble.com/bug-in-residue.m-tf4475396.html Can any confirm they get the same result? -- View this message in context: http://www.nabble.com/trouble-with-Octave-tf4502540.html#a12841144 Sent from the fink-users mailing list archive at Nabble.com. - This SF.net email is sponsored by: Microsoft Defy all challenges.

(and by the way, he is also using Octave 2.9.13 on Mac OS X) Can any confirm they get the same result? Sure I But as said, this is an upstream problem, not fink's !
