A naive question. What is the relationship between Singular Value and
Eigenvalue ?
Does every matrix has singular values ?
Does every matrix has Eigenvalues ?
When two of them are same ?
Thanks. |

I think any matrix has singular value, if the matrix also have eigenvalue,
when
two of them are same ?

It has n eigenvalues,although some may be the same.
