Describe your issue.

The docstring for factorial2 says:

If n < 0, the return value is 0.

However directly below that in the code, we can see this is not the case for n==-1

if exact:
    if n < -1:
        return 0
    if n <= 0:
        return 1

Hi,

There are still parts of boost library that are used inside mlpack, more specifically in here

• mlpack/src/mlpack/core/tree/cosine_tree/cosine_tree.hpp boost::heap
• mlpack/src/mlpack/core/data/load_arff.hpp boost::tokenizer
• mlpack/tests/main_tests/emst_test.cpp boost::math::iround()
• mlpack/core/tree/cosine_tree/cosine_tree.cpp boost::m

Current implementation of join can be improved by performing the operation in a single call to the backend kernel instead of multiple calls.

This is a fairly easy kernel and may be a good issue for someone getting to know CUDA/ArrayFire internals. Ping me if you want additional info.

Today I was checking out the library and MSVC warns for https://github.com/alandefreitas/matplotplusplus/blob/359a775710e1b1fd5667281a0855806f149b7ab0/source/matplot/util/contourc.cpp#L1771

BOUNDARY_S returns a bool do the expression is bool > 0

Currently spack does not support the following packages, all of these packages are installed outside of Spack at Cori, we would like to get support for these packages if possible.

• cpmd https://www.lcrc.anl.gov/for-users/software/available-software/cpmd/
• ComputeCPP https://github.com/codeplaysoftware/computecpp-sdk need to confirm link
• ds9 https://sites.google.com/cfa.harvard.

Add #[track_caller] to some panicking methods. Slicing methods seem the most prudent (Index/Mut does not apply, sorry).

Needs benchmarks to investigate impact, preferably holistic benchmarks.

In terms of functionality, the mid-term end goal is to achieve an offering of ML algorithms and pre-processing routines comparable to what is currently available in Python's scikit-learn.

These algorithms can either be:

• re-implemented in Rust;
• re-exported from an existing Rust crate, if available on crates.io with a compatible interface.

Description

Test default default cases (corresponding to non-existing enum values) for strongly typed enum serialization.

Expected behavior

Default cases should also be tested.

Actual behavior

Default cases are not being tested because the set of enum values for testing are systematically built using enum values corresponding to existing cases, e.g.

  const std::se
