| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | That is, eig(), eigh(), qr(), slogdet(), and svd(). For those functions that return non-tuples with certain keyword arguments, the return type is unchanged. This change should be completely backwards compatible. The namedtuple attribute names come from the array API specification (see, e.g., https://data-apis.org/array-api/latest/extensions/generated/signatures.linalg.eigh.html), with the exception of eig() which is just the same as eigh(). The name of the namedtuple object itself is not part of the specification or the public API. I have not used a namedtuple for the tuple output for qr(mode='raw'), which returns (h, tau). This updates the docstrings to use the updated namedtuple return names, and also the examples to use those names more consistently. This also updates the tests to check each function for the namedtuple attributes at least once.

* | | ENH: Improve performance of finfo and _commonType (#23088)Pieter Eendebak2023-02-151-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The finfo contains a cache for dtypes, but the np.complex128 dtype does not end up in the cache. The reason is that the np.complex128 is converted to np.float64 which is in the cache. Performance improvement for finfo(np.complex128): Main: 2.07 µs ± 75 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each) Pr: 324 ns ± 28.9 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each) Improve performance of finfo by making the cache check the first action in the __new__ Improve performance of _commonType by re-using the expression for a.dtype.type and eliminating variables The finfo and _commonType was part of the computatation time in lstsq when using scikit-rf. Since these methods are used in various other methods performance can improve there slightly as well.

* | | | BLD: enable building NumPy with MesonRalf Gommers2022-11-251-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables building with NumPy on Linux and macOS. Windows support should be complete to, but is untested as of now and may need a few tweaks. This contains: - A set of `meson.build` files and related code generation script tweaks, header templates, etc. - One CI job on Linux - Basic docs on using Meson to build NumPy (not yet integrated in the html docs, it's too early for that - this is for early adopters right now). The build should be complete, with the major exception of SIMD support. The full test suite passes. See gh-22546 for the tracking issue with detailed notes on the plan for switching NumPy to Meson as its build system. Co-authored-by: Stefan van der Walt <stefanv@berkeley.edu>

* | ENH: Fix pointer size determination for cross buildHood Chatham2022-06-111-1/+2
|/ | | | | | | | | Using `sys` to ask about the build Python is hostile to cross building because it is very hard to replace the sys module with one that gives info about the target system. On the other hand, the sysconfig data can be replaced by setting _PYTHON_SYSCONFIGDATA_NAME. So instead of using `sys.maxsize` to determine pointer size, use `sysconfig.get_config_var("SIZEOF_VOID_P")`
