libctl 3.0.1
5/1/2006
- Change shared-library version to 3:0:0 instead of 0:0:0. This avoids conflicts with shared library version numbers that has been assigned to earlier versions of libctl for Debian; thanks to Josselin Mouette for the suggestion.
libctl 3.0
4/1/2006
- Switch to use
automake
andlibtool
. Can now install shared libraries with--enable-shared
. - License is now GNU GPL (v2 or later) rather than the GNU LGPL, due to use of third-party GPL code for multi-dimensional integration (below).
-
gen-ctl-io
now supports separate generation of code and header files via--code
and--header
arguments. (Better for parallel make.) Also support a-o
option to give a different output file name. -
gen-ctl-io
can now export C++ code by using the--cxx
flag. -
gen-ctl-io
can now export SWIG.i
files for automatic type conversion in SWIG wrapper generation, using the--swig
flag. - Backwards incompatible change: users must include their own
ctl-io.h
*before*ctlgeom.h
, or you getctlgeom-types.h
instead (this is for use with the "stand-alone"libctlgeom.a
library below. - New multi-dimensional integration routines using adaptive cubature. (Much more efficient than nested 1d integrations.) Adapted in part from the HIntlib Library by Rudolf Schuerer and from the GNU Scientific Library (GSL) by Brian Gough.
- New
interpolate-uniform
function that tries to maintain a uniform distance between points (i.e. variable number of interpolated points between different list elements, as needed). - Now install a "stand-alone"
libctlgeom.a
library to make it easier to call geometry routines from non-Scheme code. - New routines to compute overlap fraction of box with object, compute analytical normal vectors, etcetera. (For upcoming versions of Meep and MPB.) Also new routines to get the object of a point, not just the material. Also new routines to operate on a supplied geometry list parameter instead of using the global; unlike the old material_of_point_in_tree functions, these functions do not shift the argument to the unit cell, but you can use the new function shift_to_unit_cell to get this behavior.
-
gen-ctl-io
now generates object equal/copy functions. - In
unit-vector3
, only return 0 when norm==0, not merely if it is small. - Added one-sided numerical derivative routine.
- Define "
verbose?
" variable corresponding to main.c variable. -
(print)
calls(flush-all-ports)
to keep C and Scheme I/O in sync. - Fix in
find-root-deriv
to prevent infinite loop in some cases where the root does not exist; thanks to XiuLun Yang for the bug report. - Bug fix in
make_hermitian_cmatrix3x3
; thanks to Mischa Megens.
libctl 2.2
9/12/2002
- Added simple trapezoidal-rule adaptive numeric integration routine.
- Numerical derivative routines now allow numerical differentation of vector-valued function. Added
deriv2
convenience routine. - Added
find-root-deriv
functions for faster root-finding of functions for which the derivative is also available. - Added missing
(cvector3 ...)
constructor, and fixed corresponding constructor forcvector3
object properties; thanks to Doug Allan for the bug report. - Added generic '
memoize
' function. - libctl programs now print out command-line parameters when they run.
- Fixed incomplete support for generic
SCM
type. - Fixed to work with Guile 1.5+ (thanks to Mike Watts for the bug report).
libctl 2.1
3/21/2002
- Bug fix: complex-number input variables were read as garbage if they had imaginary parts; does not affect complex-number outputs.
- Added generic
SCM
type for i/o variables and parameters, as a catch-all for other Scheme objects. -
main.c
now hasctl_export_hook
(enabled by definingCTL_HAVE_EXPORT_HOOK
) with which to define additional Guile symbols. -
gen-ctl-io
: converts "!" in symbols to "B" in C identifiers.
libctl 2.0
3/10/2002
- New
set-param!
function, analogous todefine-param
, that allows you to change the value of a parameter in a way that can still be overridden from the command line. - In libgeom, allow user to specify the resolution instead of the grid-size. New
no-size
support in lattice class to reduce dimensionality, and new(get-grid-size)
function. - Support for Scheme complex numbers, along with a few new associated functions:
conj
,vector3-cdot
,matrix3x3-adjoint
. - New functions to compute numerical derivatives using Ridder's method of polynomial extrapolation.
- Documented
object-property-value
; thanks to Theis Peter Hansen for the suggestion. - Get rid of unneeded make-default, and use consistent syntax for
define-property
and define-post-processed-property, compared todefine-input-var.
Not backward compatible (for developers; users are not affected). Thanks to Theis Peter Hansen for the suggestion. - Call
ctl_stop_hook
even with--help
,--version
, etcetera; this makes the behavior nicer e.g. with MPI.
libctl 1.5
11/15/2001
-
geometry-lattice
now has a separatebasis-size
property, so that you can specify the basis vectors as being something other than unit vectors. - More functions are tail-recursive, helping to prevent stack overflows; thanks to Robert Sheldon for the bug report.
- New
fold-left
andfold-right
functions, documented in the manual. - The configure script now checks that
guile
is in the$PATH
. Thanks to Bing Li and Giridhar Malalahalli for their bug reports.
libctl 1.4.1
7/4/2001
- Support function lists.
libctl 1.4
2/23/2001
- Renamed
display-many
function to more felicitousprint
and addedprint-ok?
global variable that allows you to disable program output. - Added support for passing
'function
types back and forth (just a SCM object pointing to a Scheme function). - Cosmetic fixes to yes/no? and menu-choice interaction functions.
- Support start/exit hooks for use e.g. with MPI.
libctl 1.3
1/7/2001
- Added improved "subplex" multidimensional optimization algorithm (for
maximize-multiple
andminimize-multiple
). - Documented
vector3-x
,vector3-y
,vector3-z
functions for extractingvector3
components.
libctl 1.2
7/9/2000
- Added new
cone
geometric object type. - Added
reciprocal->cartesian
,cartesian->lattice
,lattice->reciprocal
, etcetera functions to libgeom for converting vectors between bases. - Added routines
rotate-vector3
androtation-matrix3x3
for rotating vectors. - Added support for returning lists from external functions.
- Fixed bug in
matrix3x3-inverse
function. - Fixed bug in find-root for converging to negative roots.
- Use Nelder-Mead simplex algorithm for multi-dimensional minimization (it seems to be more robust than the old routine).
libctl 1.1.1
1/28/2000
- Use
CPPFLAGS
environment variable instead of the less-standardINCLUDES
to pass-I
flags to the configure script (for header files in non-standard locations). - Compilation fixes. We need to set
SHELL
in the Makefile for make on some systems. Also added rule to insurectl-io.h
is created before main.c is compiled. Thanks to Christoph Becher for the bug reports.
libctl 1.1
1/2/2000
- geom: radius and height of objects is now permitted to be zero.
- geom: material_of_point_* routines now report whether the point is in any object; necessary for use with MPB 0.9.
- Added man page for
gen-ctl-io
, based on a contribution by James R. Van Zandt.
libctl 1.0.1
11/22/1999
- geom: handle case where
ensure-periodicity
is false. - geom: bug fix in
geometric-objects-lattice-duplicates
for non-orthogonal lattices; thanks to Karl Koch for the bug report.
libctl 1.0
11/19/1999
- Initial public release.
