Import Debian changes 3a1-4.2debian/3a1-4.2

slib (3a1-4.2) unstable; urgency=low

  * Non-maintainer upload.
  * Add guile.init.local for use within the build dir, since otherwise we
    have an (earlier unnoticed) circular build-dep due to a difference
    between scm and guile.

slib (3a1-4.1) unstable; urgency=low

  * Non-maintainer upload.
  * Build-depend on guile-1.6 instead of scm, since the new version of
    scm is wedged in unstable (closes: #281809).

slib (3a1-4) unstable; urgency=low

  * Also check for expected creation on slibcat. (Closes: #240096)

slib (3a1-3) unstable; urgency=low

  * Also check for /usr/share/guile/1.6/slib before installing for guile
    1.6. (Closes: #239267)

slib (3a1-2) unstable; urgency=low

  * Add format.scm back into slib until gnucash stops using it.
  * Call guile-1.6 new-catalog (Closes: #238231)

slib (3a1-1) unstable; urgency=low

  * New upstream release
  * Remove Info section from doc-base file (Closes: #186950)
  * Remove period from end of description (linda, lintian)
  * html gen fixed upstream (Closes: #111778)

slib (2d4-2) unstable; urgency=low

  * Fix url for upstream source (Closes: #144981)
  * Fix typo in slib.texi (enquque->enqueue) (Closes: #147475)
  * Add build depends.

slib (2d4-1) unstable; urgency=low

  * New upstream.

slib (2d3-1) unstable; urgency=low

  * New upstream.
  * Remove texi2html call in debian/rules.  Now done upstream.  Add make
    html instead.
  * Changes to rules and doc-base to conform to upstream html gen
  * Clean up upstream makefile to make sure it cleans up after itself.

+@code{(require 'determinant)}
+@ftindex determinant
+
+@noindent
+A Matrix can be either a list of lists (rows) or an array.
+As with linear-algebra texts, this package uses 1-based coordinates.
+
+
+@defun matrix->lists matrix
+
+Returns the list-of-lists form of @var{matrix}.
+@end defun
+
+@defun matrix->array matrix
+
+Returns the (ones-based) array form of @var{matrix}.
+@end defun
+
+@defun determinant matrix
+
+@var{matrix} must be a square matrix.
+@code{determinant} returns the determinant of @var{matrix}.
+
+@example
+(require 'determinant)
+(determinant '((1 2) (3 4))) @result{} -2
+(determinant '((1 2 3) (4 5 6) (7 8 9))) @result{} 0
+@end example
+@end defun
+
+@defun transpose matrix
+
+Returns a copy of @var{matrix} flipped over the diagonal containing the 1,1
+element.
+@end defun
+
+@defun matrix:product m1 m2
+
+Returns the product of matrices @var{m1} and @var{m2}.
+@end defun
+
+@defun matrix:inverse matrix
+
+@var{matrix} must be a square matrix.
+If @var{matrix} is singlar, then @code{matrix:inverse} returns #f; otherwise @code{matrix:inverse} returns the
+@code{matrix:product} inverse of @var{matrix}.
+@end defun
