Forgot to add master file contents.rst for the documentation to the repo.	d-orban	More...				almost 18 years ago
o Added the possibility to assign a common value to a whole submatrix with fancy indexing, e.g., A[:3,:3] = 6, A[n:,:m] = 1, etc. o Added method __imul__ to PysparseMatrix class to allow operations like A[:10,:10] *= 2. Under the hood, this calls scale(). o Updated the html and pdf documentation for all that. o Added blurbs on sparse matrix formats to the documentation.	d-orban	More...				almost 18 years ago
- Added Numpy arrays to the list of objects that can be used to index a sparse matrix. The documentation has an example. - Added a front page for the new website. - Added the PDF manual to the Doc directory.	d-orban	More...				almost 18 years ago
+ Added to the documentation, including updated comparisons with Matlab + Fixed the layout of the html documentation so the sidebar is properly placed + Fixed docstring and tests of pysparseSuperLUSolver and pysparseUmfpackSolver + Updated setup.py so a user can link to his/her own UMFPACK + Moved the 'irsteps' optional argument from the factorize() method to the solve() method in UMFPACK.	d-orban	More...				almost 18 years ago
o Updated Python/Matlab comparisons in the documentation o Fixed some doc strings in PysparseMatrix and the direct solvers o Added Lib/poisson_vec.py and Lib/poisson.m	d-orban	More...				almost 18 years ago
o Added comments to the general pysparseMatrix methods and thus to the documentation, In the documentation of a class, is it appropriate to use Sphinx markup, or is it too difficult to read? o Added examples related to the LU factorizations, o Played with the stylesheet of the docs a bit.	d-orban	More...				almost 18 years ago
o Improved the efficiency of fancy indexing, especially when both index sets are Python slices. There are still aspects to improve.	d-orban	More...				almost 18 years ago
o Added fancy indexing to ll_mat matrices. Most of it carries over to PysparseMatrix instances, o Started some documentation based on the Sphinx framework, located in Doc/pysparse. The ReST source files are in Doc/pysparse/source. In Doc/pysparse, type 'make html' or 'make latex'.	d-orban	More...				almost 18 years ago
bumped version number to 1.2a1	wd15	More...				almost 18 years ago
- Added a find() method to ll_mat objects and PysparseMatrix objects - Fixed the examples in the PysparseMatrix class definition - Added a PysparseMatrix + scalar method in __add__. This operation adds the scalar to all nonzero elements of the sparse matrix, so the result is a sparse matrix.	d-orban	More...				almost 18 years ago
Fixed size errors in __mul__ and __rmul__ methods of PysparseMatrix.	d-orban	More...				almost 18 years ago
Default value of use_users_superlu set to False in setup.py.	d-orban	More...				about 18 years ago
Converted private symbols into public symols in sparseMatrix.py and pysparseMatrix.py. Updated the SuperLU and UMFPACK classes as well as the test classes.	d-orban	More...				about 18 years ago
By default, use the version of SuperLU supplied with Pysparse. The variables superlu_include_dirs, superlu_src_dir, superlu_lib_dir and superlu_libraries now have (slightly) more sensible values. The user will however need to give them values appropriate for his/her system.	d-orban	More...				about 18 years ago
- Added abstract sparse matrix class taken from Fipy and slightly modified. - Added abstract directSolver class. SuperLU and UMFPACK are now subclasses of directSolver. They are defined in pysparseSuperLU and pysparseUmfpack. - setup.py now lets the user build against the latest sources of SuperLU by setting the use_users_superlu variable to True (see setup.py). The new superlu3module.c realizes the interface. - Added test classes to demo pysparseSuperLU and pysparseUmfpack. - Updated umfpackmodule.c to return factors and info on the factorization.	d-orban	More...				about 18 years ago
