示例1: updateEigenSystem
bool updateEigenSystem(unsigned max_tries, unsigned max_iters) {
if (max_iters==0) max_iters = 30 * p.n;
static double lastGoodMinimumEigenValue = 1.0;
/* Try to get a valid calculation */
for (unsigned tries = 0; tries < max_tries; ++tries) {
unsigned iters = eig( p.n, C, d, B, max_iters);
if (iters < max_iters)
{ // all is well
/* find largest/smallest eigenvalues */
double minEV = d.min();
double maxEV = d.max();
/* (MK Original comment was) :Limit Condition of C to dMaxSignifKond+1
* replaced dMaxSignifKond with 1./numeric_limits<double>::epsilon()
* */
if (maxEV * numeric_limits<double>::epsilon() > minEV) {
double tmp = maxEV * numeric_limits<double>::epsilon() - minEV;
minEV += tmp;
for (unsigned i=0;i<p.n;++i) {

}
} /* if */

//flgEigensysIsUptodate = 1;
//genOfEigensysUpdate = gen;
//clockeigensum += clock() - clockeigenbegin;

} /* if cIterEig < ... */
// numerical problems, ignore them and try again
/* Addition des letzten minEW auf die Diagonale von C */
/* Add the last known good eigen value to the diagonal of C */
double summand = lastGoodMinimumEigenValue * exp((double) tries);
for (unsigned i = 0; i < p.n; ++i)

} /* for iEigenCalcVers */
