Creates a temporary matrix of possibly uninitialized values, from the given memory stack.

Warning

Working with uninitialized values is trickier in Rust than other languages. In particular, references must always point to initialized data, which means that using MatMut::get, MatMut::get_unchecked, the indexing operator, etc., on the resulting matrix can cause undefined behavior.

Use the pointer access API instead: e.g., MatMut::ptr_at or zip::MatUninit.
