make all permutation matrices column permutations (bug #42418)
Making all permutation matrices column permutations allows permutation
matrices to be iterated over in column-major order just like any other
matrix.
* PermMatrix.h, PermMatrix.cc (PermMatrix::_colp): Delete member
variable and all uses.
(PermMatrix::transpose): Create new matrix with internal
representation flipped.
(PermMatrix::pos_power): New function.
(PermMatrix::eye): Call the one-argument constructor which already
defaults to the identity matrix.
(PermMatrix::is_col_perm): Unconditionally return true.
(PermMatrix::is_row_perm): Unconditionally return false.
(PermMatrix::data, PermMatrix::fortran_vec, PermMatrix::pvec): Delete.
(PermMatrix::col_perm_vec): New function.
* lu.cc: New test.
* base-lu.cc (base_lu<lu_type>::base_lu): Call transpose in ipvt
initialization.
* find.cc, kron.cc, pr-output.cc, ov-perm.cc, PermMatrix.cc,
PermMatrix.h, Sparse.cc, dMatrix.cc, fMatrix.cc, CmplxQRP.cc,
base-lu.cc, dbleQRP.cc, fCmplxQRP.cc, floatQRP.cc,
Sparse-perm-op-defs.h, mx-op-defs.h: Adapt to PermMatrix changes.
