Hi All,
Is there any way to call function lu() or luinc() in single precision? I think that single precision is enough for my problems, but MATLAB uses double precision as default. In advance, thanks for your comments.

some_single_data = single(rand(20,20));
[L, U, p] = lu(some_single_data);
class() of each of the outputs will report single . I do not know if double precision is used internally.
