ippiEigenValsVecs

Hi,

In documentation it states the following:

In case of a singular matrix or when one eigen value is much smaller than the second one, all these six values are set to 0.

Q: It is possible the casewhere one eigen value is much smaller than the second one to obtain the eigen values and the eigen vectors, instead ofsetting all values to 0?

Or, maybeyou can provide such a function in future versions of Ipp?

Regards, Ciprian

Sorry to insist,

I would like more information on this function.

What does it means "much smaller then the second one", ten times, a hundred times?

What is the scheme used to compute the eigen vectors?

Thank you.

Regards, Ciprian

Ciprian, I'm sorry for the delay, still waiting more details from our experts
