* ENH: inv/solve work with empty inner and others empty outer arraySebastian Berg2013-08-042-16/+82
| | | | | | | 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: Remove uses of the WarningManager class.Charles Harris2013-07-1212-150/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WarningManager was a workaround for the lack of the with statement in Python versions < 2.6. As those versions are no longer supported it can be removed. Deprecation notes are added to WarningManager and WarningMessage, but to avoid a cascade of messages in third party apps, no warnings are raised at this time, that can be done later. Closes #3519.
* | | MAINT: Fix Python version dependent test.Charles Harris2013-07-121-16/+17
|/ / | | | | | | | | | | | | | | | | The buffer test in numpy/core/tests/test_api.py was apparently testing for incorrect behavior that was corrected in Python 2.7.5. This PR changes the test to check for the correct results and makes running it depend on Python version. Closes #3512.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | MAINT: Remove outdated version checks.Charles Harris2013-07-1129-317/+16
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | Because Numpy 1.8.0 will no longer supports Python versions < 2.6 we no longer need to check for that and can also remove the code that is specific to those earlier versions. To make this a bit safer, the toplevel setup.py file now contains a check of the Python version number and raises an error when run by an unsupported version.

| | | | | | | | | | | | Check if object is of array dimension zero, then avoid heavy calls like PyArray_FromAny. Hence passing obj to out_op PyArrayObject unchanged. Also PyArray_FromAny(obj,NULL,0,0,0,NULL) calls PyArray_FromArray(obj,NULL,0) which return original obj

* | | BUG: Fix failure to return monic polynomials from roots.Charles Harris2013-07-022-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug affected the various polynomial class methods fromroots due to the ability to specify both window and domain. In that circumstance the roots are mapped from the domain to the window by the substitution `x = off + scl*x`. The polynomial that was being generated was monic in the window before substitution, but if scl was not one it was not monic considered as a function of the variable x in the domain. The fix is to divide the generated coefficients by `scl ** deg` so that the scaling of the highest degree term after substitution is canceled. It might be better to make the scaling optional in the future, but this fix makes the result match the documentation. Closes #3467.
