* | ENH: use PyDataMem_NEW_ZEROED for PyArray_ZerosJulian Taylor2013-08-162-11/+52
| | | | | | | | | | | | | | | | | | PyDataMem_NEW_ZEROED uses calloc which will take advantage of the fact that most operating systems provide already zero initialized memory blocks on larger allocations. Additionally this memory can be sparse (= mapped to a single zero page) on some systems (e.g. linux) reducing memory usage of applications using sparse arrays.
* | ENH: add PyDataMem_NEW_ZEROED which allocates memory with callocJulian Taylor2013-08-163-2/+23

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.
| * | | TST: Add more extensive tests for the mean, var, and std methods.Charles Harris2013-08-122-1/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Test the mean, var, and std methods more extensively. In addition, add tests that: Check that scalar return types ar what they should be. Check that ValueError is raised when ddof is too big.
| * | | ENH: Make var and std methods raise error when ddof too big.Charles Harris2013-08-121-23/+29
| | | | | | | | | | | | | | | | | | | | Currently the results may be infinite or negative. Instead, raise a ValueError in this case.

| | | | | | | | | | | | | | | | | | | | The return type could differ depending on whether or not the value was a scalar.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use issubclass instead of issubdtype. Add some blank lines. Remove trailing whitespace. Remove uneeded float casts since true_divide is default. Clean up documentation a bit.
