Indices in IPIV array for LU related functions

Postby jgpallero » Mon Jan 06, 2014 11:18 am

Hello,

All LU (and also QR with column pivoting) related LAPACK functions has as an argument an array IPIV that stores the indices of row (columns for QR) permutations. In the C interface of CULA, are the indices of this array 0-based or 1-based, as in Fortran?, i.e., an index for the first row , is stored as 0 or as 1?

Thanks
