Consider the following simple example (Windows 10, MA 11.3)

mat = Table[RandomReal[], {i, 1, 2000}, {i, 1, 2500}];
{u, ww, vt} = SingularValueDecomposition[mat];

After the SingularValueDecomposition finishes, Mathematica makes a "ding" sound and the kernel quits. My system has a lot of RAM and it does not look like it is close to running out. What may be the reason for the crash, and how to fix this?

EDIT:

As pointed out by rhermans, the random example does not always produce a crash, so I have uploaded an example matrix here:

https://gofile.io/?c=k06dAL

that produces such a crash on a fresh kernel.

EDIT2:

SeedRandom[1000]
mat = Table[RandomReal[], {i, 1, 2000}, {i, 1, 2500}];
{u, ww, vt} = SingularValueDecomposition[mat];

also seems to consistently crash in this fashion.

  • $\begingroup$ Can't reproduce your problem neither in Mathematica 11.3 nor 12 on Windows 7 64. Does it happens with a fresh kernel? Can you reproduce it with a particular SeedRandom? $\endgroup$ – rhermans Aug 20 '19 at 14:07
  • $\begingroup$ @rhermans It happens on a fresh kernel with the following mat gofile.io/?c=k06dAL , now the file appears to have posted. $\endgroup$ – Kagaratsch Aug 20 '19 at 14:34
  • $\begingroup$ It would be easier if you gave a SeedRandom than asking people to download a file. $\endgroup$ – rhermans Aug 20 '19 at 14:36

    $\begingroup$ @rhermans on my end SeedRandom[1000] also seems to cause such a crash consistently. $\endgroup$ – Kagaratsch Aug 20 '19 at 14:41
