Libctl release notes

From AbInitio

Here, we describe what has changed between releases of the libctl package. You can also refer to the NEWS file in the libctl package (or the ChangeLog file for a more detailed listing).

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 for cvector3 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 has ctl_export_hook (enabled by defining CTL_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 to define-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 to define-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 separate basis-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 and fold-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 felicitous print and added print-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 and minimize-multiple).
• Documented vector3-x, vector3-y, vector3-z functions for extracting vector3 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 and rotation-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-standard INCLUDES 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 insure ctl-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.
