test_eigen_ref_life_support()

def test_eigen_matrix.test_eigen_ref_life_support

(

)

Ensure the lifetime of temporary arrays created by the `Ref` caster

The `Ref` caster sometimes creates a copy which needs to stay alive. This needs to
happen both for directs casts (just the array) or indirectly (e.g. list of arrays).

test_negative_stride_from_python()

def test_eigen_matrix.test_negative_stride_from_python

(

msg

)

Eigen doesn't support (as of yet) negative strides. When a function takes an Eigen matrix by
copy or const reference, we can pass a numpy array that has negative strides.  Otherwise, an
exception will be thrown as Eigen will not be able to map the numpy array.
