Detailed Description

tests the characteristic polynomial of sparse and special matrices

Warning

gcc-4.2 produces bad optimized code there

Bug:

occasionnnaly there is a "SIGFPE, Arithmetic exception." in CRA

testRandomCharpoly is not always tested !!

Test:

characteristic polynomial of some matrices (sparse, special)
