| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The worst case of alternating masked iterated all boundaries and sliced half away, improve this by only iterating the needed half of the boundary index array.

So even though we have a slower loop over the rows now ... this code snippet runs about 3 times faster than before. However the speed improvement of the whole function is not really significant because cov() takes 80-99% of the time (dependent on blas/lapack implementation and number of CPU cores). More important is that we will safe 1/3 memory. For example corrcoef() for a [23k, m] matrix needs 8GB now instead of 12GB.

| * | | | | | | | | | | BUG: Fixed string representation of mvoid with multi-dimensional columnsThomas Robitaille2015-10-042-25/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a bug that caused the string representation of masked structured array rows with multi-dimensional columns to fail (numpy/numpy#6019), and includes a regression test. Since __repr__ suffered from a similar bug, and since previously __repr__ returned the same as __str__ for mvoid, we now set __repr__ to reference the same method as __str__.

However, all the online documentation states that it will return either a 0 or a nonzero value, which seems to be determined by the OS. These changes allow the code to work with a zero or a nonzero value.
