Module Name: pkgsrc Committed By: jtb Date: Tue Apr 29 22:15:28 UTC 2003 Modified Files: pkgsrc/math/algae: Makefile PLIST distinfo pkgsrc/math/algae/patches: patch-ab patch-ac patch-ae Added Files: pkgsrc/math/algae/patches: patch-af Log Message: Update to version 4.1.2. Changes include: * New try/catch mechanism for control of exception handling. * Fixed memory leaks in solve and svd. * Builtin `tril' and `triu' functions -- sparse arrays stay sparse. * Fixed integer overflow problems in `band' and `cram'. * Incorporated the SuperLU package for solving sparse linear systems. Previously, sparse systems were converted to dense and solved with LAPACK (unless configured with BCSLIB-EXT). * Included support for memory allocation debugging with dmalloc. * Improved the logical operations to do a much better job at maintaining sparsity. * New standard function `select'. * Changes to the matrix bandwidth minimization code. The old `band' function is now called `gpskca' and can do either profile or bandwidth minimization of symmetric or hermitian matrices. Matrix statistics are computed by the new `band' function. * New standard functions `linspace' and `logspace'. * New standard function `equilibrate' computes scale factors to improve the condition of a matrix. However, sparse code has not yet been included. * Fixed several deficiencies in the `transform' function. * Removed old get_ascii and put_ascii functions. I doubt if anyone has used these in the last decade. To read and write matrices in text files, use the algae MatrixMarket package. * Fixed several errors with hermitian symmetry. * Fixed mishandling of sparse matrix multiplication case where non-zero factors give a zero result. * Added "short-circuit" logical operators && and ||. * Added the `cram' builtin function -- it's the same as `form' except the output array is sparse when that makes sense. * Added the `product' user function -- product of array elements. * Added `mksparse' and `exsparse' functions for converting matrices to and from coordinate form. * Switched to LAPACK's DGGEV now that DGEGV is deprecated. Also use the new workspace size query feature in LAPACK, rather than working it out ourselves. * Use LAPACK's ZHEGV and ZGGEV for complex generalized eigenvalue problems. * Use floating point exception support from glibc 2.2 on Linux. * Improved accuracy and behavior for complex arguments in functions `log', `asin', and `acos'. * Added inverse hyperbolic trig functions `asinh', `acosh', and `atanh'. * Various minor bug fixes.
