This is a crazy problem. At first I thought it was caused by corrcoef(), then I realized that corrcoef() is using cov() and I found that cov() was also seg faulting. Then I looked at cov and saw the inner product and discovered that the inner product was seg faulting. So, basically, matrix multiplication is causing seg faults, but it depends strongly on the size of the matrix.
So the seg faults occur only if BOTH rows>39 AND cols>38, and the more rows there are, the fewer columns can be supported. I'm guessing the problem is with libraries or with LAPACK or ATLAS. Mike
not such problem on cygwin with octave-3.4.2 and lapack 3.2.2 Wich version of lapack are you using ? Regards Marco
