Notes

This function requires Jacket DLA. X must be square and non-sparse.

Technical Note: MATLAB sorts Eigen values while the corresponding implementation by CULA does not. As a result, it is better to check the full reconstructions against each other.

For example:

X = gsingle(rand(3));
[V D] = eig(X);
% recast to double for best reconstruction
% Check X*V against V*D.
