[petsc-users] Functions for judging the properties of the matrix

[w_ang_temp]

 
Hello,
   
    Is there function in PETSc for judging the properties of the matrix A ? 
Such as positive definitiveness and
 
conditional number. I know that there are several functions begin with MatIs+, 
but it has limited amounts. 
 
    Thanks.
 
                                                   Jim
