All calls to "find" use the same generic implementation (bug #42408, 42421)
* find.cc: Rewrite.
Move generic "find" logic to find.h
(Ffind) : Changed calls to find_nonzero_elem_idx to find_templated
Added unit test for bug #42421
* Array.cc (and .h) (Array::find): Deleted function. Replaced with find::find(Array)
from find.h
* Array.h: Added typedef for array_iterator (in nz-iterators.h) as
Array::iter_type
* DiagArray2.h: Added typedef for diag_iterator (in nz-iterators.h) as
DiagArray2::iter_type
* PermMatrix.h: Added typedef for perm_iterator (in nz-iterators.h) as
PermMatrix::iter_type
Also added typedef for bool as PermMatrix::element_type
(not octave_idx_type)
Added an nnz() function (which is an alias for perm_length) and a
perm_elem(i) function for retrieving the ith element of the permutation
* Sparse.h: Added typedef for sparse_iterator (in nz-iterators.h) as
Sparse::iter_type
Added a short comment documenting the the argument to the numel
function
* idx-vector.cc (idx_vector::idx_mask_rep::as_array): Changed Array.find to
find::find(Array) (in find.h)
* (new file) find.h
* (new file) interp-idx.h: Simple methods for converting between interpreter
index type and internal octave_idx_type/row-col pair
* (new file) min-with-nnz.h: Fast methods for taking an arbitrary matrix M and
an octave_idx_type n and finding min(M.nnz(), n)
* (new file) nz-iterators.h: Iterators for traversing (in column-major order)
the nonzero elements of any array or matrix backwards or forwards
* (new file) direction.h: Generic methods for simplifying code has to deal with
a "backwards or forwards" template argument
* build-sparse-tests.sh: Removed 5-return-value calls to "find" in unit-tests;
Admittedly this commit breaks this "feature" which was undocumented and only
partially supported to begin with (ie never worked for full matrices,
permutation matrices, or diagonal matrices)
