* | BUG: Make DeprecationWarning always raise error in test.Charles Harris2013-08-311-3/+5
| | | | | | | | | | | | The test_fancy in numpy/lib/tests/test_function_base.py failed in release because a DeprecationWarning was no longer raised, it had become a warning.
* | Small correction in the docstring of polyfit. As mentionned in Issue 3640, ↵Matthieu Dartiailh2013-08-251-3/+3

* DEP: Make nansum return 0 for all-NaN or empty axis.Charles Harris2013-08-182-39/+12
| | | | | Make this happen and remove test parts dependent on numpy version < 1.9. Fixes test failures in numpy after 1.8 branch.
* STY: Giant comma spacing fixup.Charles Harris2013-08-1831-875/+875
| | | | | | | 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.

* DOC: Various fixes.Charles Harris2013-08-142-19/+18
| | | | | | Fix typos and clarify some explanations. Document the changes in the return values of nanargmin and nanargmax for all-NaN slices in the 1.8.0 release notes.

* MAINT: Refactor nanfunctions.Charles Harris2013-08-121-333/+468
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nanmax, nanmin -------------- Add out and keepdims keywords. nanargmin, nanargmax -------------------- A NanWarning is raised if an all NaN slice detected. For all such slices np.iingo(np.intp).min is returned as the index value. nansum ------ The keywords dtype, out, and keepdims are added. A FutureWarning is raised, as in the future the mean of an empty slice after NaN replacement will be 0 instead of the current NaN. nanmean, nanvar, nanstd ----------------------- For all, if the input array is of inexact type then the dtype and out parameters must be of inexact type if specified. That insures that NaNs can be returned when appropriate. The nanmean function detects empty slices after NaN replacement and raises a NanWarning. NaN is returned as the value for all such slices. The nanmean and nanstd functions detect degrees of freedom <= 0 after NaN replacement and raise a NanWarning. NaN is returned as the value for all such slices.
* MAINT: Separate nan functions into their own module.Charles Harris2013-08-125-463/+935
| | | | | | | | | | | | | | New files lib/nanfunctions.py and lib/tests/test_nanfunctions.py are added and both the previous and new nan functions and tests are moved into them. The existing nan functions moved from lib/function_base are: nansum, nanmin, nanmax, nanargmin, nanargmax The added nan functions moved from core/numeric are: nanmean, nanvar, nanstd
* ENH: implement median in terms of partitionJulian Taylor2013-08-122-12/+79
| | | | | | Partitioning is sufficient to obtain the median and is much faster. In the case of overwrite_input=True the resulting array will not be fully sorted anymore.

* | MAINT: Remove uses of the WarningManager class.Charles Harris2013-07-122-32/+12
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Harris2013-07-111-3/+0
|/ / | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | np.pad will now accept a pad_width containing zeros. The functionality was already implemented, but validation of input was too strict.
* | BUG: Make np.load transfer file ownership to the returned NpzFile.Charles Harris2013-06-222-5/+22
| | | | | | | | | | | | | | This assures that when the loaded file is closed it also closes the file descriptor, avoiding a resource warning in Python3. Closes #3457.

| | | | | | | | | | | | | | | | | | Maximum data size limitations in the crc32 module cause errors when reading more than 2 ** 32 bytes from gzip streams. Work around this issue when reading large arrays from npz files by chunking reads to 256mb. This appears to resolve bug #2922.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct the implementation of the npv function, its documentation, and the mirr function that depends on it. The test_financial.py is also corrected to take into account those modifications The npv function behavior was contrary to what the documentation stated as it summed indexes 1 to M instead of 0 to M-1. The mirr function used a corrective factor to get the correct result in spite of that error so that factor is removed. Closes #649

| * | ENH: improved, faster algorithm for array paddingJosh Warner (Mac)2013-05-192-429/+1102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New padding method which scales much better with dimensionality. This new implementation is fully vectorized, builds each abstracted n-dimensional padding block in a single step, and takes advantage of separability. The API is completely preserved, and the old algorithm is used if a vector function is input for `mode`. The new algorithm is faster for all tested combinations of inputs, and scales much better with dimensionality. Execution time reductions from ~25% for small rank 1 arrays to >99% for rank 4+ arrays observed.
