*STEVR documentation on VL/VU vs. referencing

Postby pav » Thu Jun 19, 2014 5:31 am

Dear Lapack authors,

The DSTEVR documentation notes that VL/VU are not referenced in A and I modes:
Code: Select all
*  VL      (input) DOUBLE PRECISION
*  VU      (input) DOUBLE PRECISION
*          If RANGE='V', the lower and upper bounds of the interval to
*          be searched for eigenvalues. VL < VU.
*          Not referenced if RANGE = 'A' or 'I'.

However, lines 326-327 in dstevr.f contain
Code: Select all
      VLL = VL
      VUU = VU

I'm not sure on the exact meaning of "not referenced" in the documentation, but in case it is intended to mean that any memory address can be passed in, here's a bug report.

Thanks Pauli. Fixed in SVN revision 1489. Julien.

Old code:
Code: Select all
     VLL = VL
     VUU = VU

New code:
Code: Select all
        VLL = VL
        VUU = VU
     END IF
