* BUG: Allos linalg.solve to handle zero equations.Sebastian Berg2013-10-011-4/+5
| | | | | This was previously correct, but the special case was missing since the gufunc code cannot handle it.
* STY: Giant comma spacing fixup.Charles Harris2013-08-181-8/+8
| | | | | | | Run the 2to3 ws_comma fixer on *.py files. Some lines are now too long and will need to be broken at some point. OTOH, some lines were already too long and need to be broken at some point. Now seems as good a time as any to do this with open PRs at a minimum.

* | ENH: inv/solve work with empty inner and others empty outer arraySebastian Berg2013-08-041-16/+34
| | | | | | | | | | | | | | This makes the inverse of a 0x0 array simply be 0x0 again. It also modifies the no-empty array check in favor of a no-empty *inner* array, since the gufuncs seem to handle the other case fine.

* | MAINT: Use np.errstate context manager.Charles Harris2013-07-111-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that Python < 2.6 is no longer supported we can use the errstate context manager in places where constructs like ``` old = seterr(invalid='ignore') try: blah finally: seterr(**old) ``` were used.

| | | | | | | | | | | | i386 does not have 16 byte long double by default (only 12 byte/float96) so the import prevents numpy startup. Introduced in 1.8.0dev 40000f508

| * | ENH: Add `raw`, `reduced`, `complete` modes to qr factorization.Charles Harris2013-04-011-34/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If K = min(M, N) where the matrix to be factored has dimensions MxN, then 'reduced' : returns q, r with dimensions (M, K), (K, N) (default) 'complete' : returns q, r with dimensions (M, M), (M, N) 'r' : returns r only with dimensions (K, N) 'raw' : returns h, tau with dimensions (N, M), (K,) 'full' : alias of 'reduced', deprecated 'economic' : returns h from 'raw', deprecated. The options 'reduced', 'complete, and 'raw' are new. The default is 'reduced' and to maintain backward compatibility with earlier versions of numpy both it and the old default 'full' can be omitted. Note that array `h` returned in 'raw' mode is transposed for calling Fortran. Both the 'full' and 'economic' modes are deprecated. For backwards compatibility the modes 'full', 'economic' may be passed using only the first letter but all others must be spelled out.
* | | 2to3: Use absolute imports.Charles Harris2013-03-281-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new import `absolute_import` is added the `from __future__ import` statement and The 2to3 `import` fixer is run to make the imports compatible. There are several things that need to be dealt with to make this work. 1) Files meant to be run as scripts run in a different environment than files imported as part of a package, and so changes to those files need to be skipped. The affected script files are: * all setup.py files * numpy/core/code_generators/generate_umath.py * numpy/core/code_generators/generate_numpy_api.py * numpy/core/code_generators/generate_ufunc_api.py 2) Some imported modules are not available as they are created during the build process and consequently 2to3 is unable to handle them correctly. Files that import those modules need a bit of extra work. The affected files are: * core/__init__.py, * core/numeric.py, * core/_internal.py, * core/arrayprint.py, * core/fromnumeric.py, * numpy/__init__.py, * lib/npyio.py, * lib/function_base.py, * fft/fftpack.py, * random/__init__.py Closes #3172
* | 2to3: Replace xrange by range and use list(range(...)) where neededCharles Harris2013-03-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In python3 range is an iterator and `xrange` has been removed. This has two consequence for code: 1) Where a list is needed `list(range(...))` must be used. 2) `xrange` must be replaced by `range` Both of these changes also work in python2 and this patch makes both. There are three places fixed that do not need it, but I left them in so that the result would be `xrange` clean. Closes #3092
* | 2to3: Put `from __future__ import division in every python file.Charles Harris2013-03-011-0/+2
| | | | | | | | | | | | | | | | This should be harmless, as we already are division clean. However, placement of this import takes some care. In the future a script can be used to append new features without worry, at least until such time as it exceeds a single line. Having that ability will make it easier to deal with absolute imports and printing updates.
