Error message: ** On entry to DGER

Postby Igor » Fri Nov 18, 2005 9:39 am


I am trying to solve a linear system using DGESV-routine. Running the code gives me an error message:

'** On entry to DGER parameter number 9 had an illegal value'

Parameter number 9 is the leading dimension of the matrix.

DGER itself is a part of BLAS, however I have no idea, what could be wrong...

Does anyone has some ideas, what I could check or change?

Thx in advance.

This alomost certainly means that you are calling DGESV incorrectly. Maybe one of the arrays is incorrectly dimensioned and so other values are getting overwitten.

A correct call to DGESV would not produce any error messages from the BLAS.

Best wishes,
