Yeah I was aiming to compute the smallest eigenvalue.
I guess my tittle was off. I was just trying to aim to the fact that the
stiffness matrix
I wrote to an output file and then I read was singular.
Abbas:
what I wanted to point out is that it's hard to establish what
"singular" actually means. *Mathematically*, singular means (or is
equivalent to) that the matrix has zero determinant. *In practice*, this
is not a criterion that can be tested numerically because floating point
numbers cannot distinguish whether the determinant is (0.1)^1000 or in
fact zero.
