libsuperlu6 binary package in Ubuntu Mantic arm64

 SuperLU is a general purpose library for the direct solution of
 large, sparse, nonsymmetric systems of linear equations on high
 performance machines.
 .
 The library is written in C and is callable from either C or Fortran.
 The library routines will perform an LU decomposition with partial
 pivoting and triangular system solves through forward and back
 substitution. The LU factorization routines can handle non-square
 matrices but the triangular solves are performed only for square
 matrices. The matrix columns may be preordered (before factorization)
 either through library or user supplied routines. This preordering
 for sparsity is completely separate from the factorization. Working
 precision iterative refinement subroutines are provided for improved
 backward stability. Routines are also provided to equilibrate the
 system, estimate the condition number, calculate the relative
 backward error, and estimate error bounds for the refined solutions.
 .
 This package contains the SuperLU shared library.
