Fri Aug 19 23:40:24 EDT 2005

indent (from a mixture of tabs, 8 space, 4 space, and 2 space)

Changes in v1.7 -- leto
Fri Mar 15 13:09:49 EST 2002
---------------------------
* each() and each_diag() are now one-based for consistency
* removed _trace() comments
* as_latex() function created
* t/latex.t created
* t/bool.t created
* t/periodic.t created

* new_from_string() shouldn't care about the case of the scientific E
notation (pointed out by Jim Bowery <jim_bowery@hotmail.com>)

is not quadratic
Changes in v1.6 -- leto
Sat Feb 16 09:46:51 EST 2002
-------------------------
* is_skew_symmetric() function added
* fixed logic error is sym_eigenvalues ( didn't notice if not square! )
* spectral_radius() function added
* is_binary() function added
* is_LR() function added
* t/spectral.t created
* t/binary.t created
* t/is_LR.t created

* is_gramian() function added
Changes in v1.5 -- leto
Sat Jan 12 04:20:48 EST 2002
-------------------------
* t/inverse.t test 6 was numerically instable, commented out
I ran it 10000 times and got values from 1e-2 to 1e-16,
this caused the test to randomly fail, because it checked
that the value was less than 1e-10
I did not notice this problem because my default perl install
has USE_LONG_DOUBLE
* changed epsilon to be 1e-8 in funcs.pl ( was 1e-10)
Changes in v1.4 -- leto
Jan 10 2002
--------------------------
* Steffen Beyer gave maintainer-ship to Jonathan Leto
* exponent() function added
* trace() function added
* "**" and "**=" overloaded to exponent()
* $matrix ** -1 is now a quick way to compute the inverse, if it exists
* new_from_rows and new_from_cols integrated from Math::MatrixReal::Ext1
* is_diagonal() function added
* is_tridiagonal() function added
* each() function added
* each_diag() function added
* put functions used by all the test scripts into funcs.pl instead
of all of them having copy+paste code
* t/inverse.t created
* t/diag.t created
* t/exponent.t created
* t/trace.t created
* t/ext1.t created
* some documentation spelling errors corrected
* perl operators exp(),sin(),cos() overloaded
only works with diagonal matrices for now
* new_diag() function added
* is_upper_triangular() function added
* is_lower_triangular() function added
* t/triang.t created
* t/det.t created
* inverse() function added
* det() function added
should be much faster for diagonal and triangular matrices
* tri_diagonalize() tri_eigenvalues() and now do real tridiag check, as per TODO
* t/minor.t created
* t/cofactor.t created
* t/adjoint.t created
* t/quadratic.t created

* swap_col() function added
* t/swap.t created
* t/orthogonal.t created
* is_orthogonal() function added
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
module directory has changed (eg. "darwin-2level" vs.
"darwin-thread-multi-2level").
binary packages of perl modules need to be distinguishable between
being built against threaded perl and unthreaded perl, so bump the
PKGREVISION of all perl module packages and introduce
BUILDLINK_RECOMMENDED for perl as perl>=5.8.5nb5 so the correct
dependencies are registered and the binary packages are distinct.
addresses PR pkg/28619 from H. Todd Fujinaka.
The automatic truncation in gensolpkg doesn't work for packages which
have the same package name for the first 5-6 chars.
e.g. amanda-server and amanda-client would be named amanda and amanda.
Now, we add a SVR4_PKGNAME and use amacl for amanda-client and amase for
amanda-server.
All svr4 packages also have a vendor tag, so we have to reserve some chars
for this tag, which is normaly 3 or 4 chars. Thats why we can only use 6
or 5 chars for SVR4_PKGNAME. I used 5 for all the packages, to give the
vendor tag enough room.
All p5-* packages and a few other packages have now a SVR4_PKGNAME.
