pub fn cholesky(a: &[Vec<Scalar>]) -> GeopResult<(Vec<Vec<Scalar>>, Vec<bool>)>Expand description
The Cholesky factor L of the symmetric a, a = L Lᵀ — leaving out
every row whose pivot could be zero or less, or is too small to divide
by: one that, in the light of
the rows before it, says nothing new (or nothing positive). Which rows
were left out is true in the second.
