Indices in IPIV array for LU related functions

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 MKL LAPACKE C interface, 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

One-based indices still so that the routines are compatible.
