| Sticky Revision: |
some new functions around tensor product added.
Modified the following python methods in escript/py_src/util.py to call faster C++ methods: escript_trace escript_transpose escript_symmetric escript_nonsymmetric
formatting errors in epydoc tags fixed
test with tagged data pass now
more copyright statements added
Corrected spelling of 'license' in url so that the link actually points to the license.
strange problem with import numarray.linear_algebra fixed
moved "import numarray.linear_algebra" to function that uses it, in case it is not installed
1D and 3D tests for eigenvalues_and_eigenvector added.
eigenvalues_and_eigenvector fucntion added. test for 2D problem is added and is passed.
problem with eigenvalue of zero matrix fixed (thanks Dr Hale)
faster version of the local eigenvalue calculation
some modifications on eigenvalues to make it a bit more robust.
more tests on slicing
symmetric and nonsymmetric part functions added
eigenvalues is working now
small bugs in eigenvalues function fixed. 3x3 on data still given wrong results
local eigenvalues added (not tested yet)
tests for __getitem__ added
transpose function added
L2 function added
kronecker (and relatives) take now a FunctionSpace as argument and return a Data object in tthis functionspace
and finally test for the divergence operator added. div() has been modified to take Symbol arguments
comprehensive testing for integrate function added. tests for grad will be added in the next check in. GradTest is obsolete now.
new function inverse and tests added
new implementation and testing for trace function
bug in CPP substitute fixed.
inner returns right functionspace now
Some chnages required for oder numarray versions. mai problem is that operations on array objects with rank 0 sometimes return float rather than arrays. This problem seems to be fixed in newer releases.
typo fixed
tests for clip, maximum, minimum added
clip added
bug fixed (thanks to Estelle)
some fixes to make the test to run for older numarray versions
fixing the problem that older versions of numarray don't have a sign method
reimplementation of maxval,minval and length. small bug in generalTensorProduct fixed
some minor bugs in util.py fixed.
move all directories from trunk/esys2 into trunk and remove esys2
