[BUG REPORT] Array index started with 1 in LAPACKE_dgeqp3()

Wei_W_7 — Thu, 27 Sep 2012 14:48:07 GMT

Sorry I failed to find a proper place to report bug on www.intel.com.

The sixth parameter of LAPACKE_dgeqp3() ("jpvt") which is an array storing sorting indices of another array. However it wrongly contains

Fortran-style indices (starting from 1) but not C-style indices.

This bug appears in both MKL 11.0 and MKL 10.0.

Thanks.

MKL implementations of netlib

MKL implementations of netlib functions are required to work the same as the netlib reference source. If it doesn't do so, you could file a bug report on premier.intel.com. If you didn't register your license, thus creating a support account, you can do so at https://registrationcenter.intel.com. If you are calling the Fortran-callable function, it should not be surprising if subscripts are Fortran compatible.

no no, you don't need submit

no no, you don't need submit the bug report on premier,intel.com because of if this is the real problem, we will take and submit it from this forum. of course if this is a real problem but I am not sure about this case. We need to check it.

Hello Wei,
