eigen - dsygv
eigen - dsygv
(OP)
Hi,
i am using fortran to solve an eigen value problem. i am using lapack routine dsygv to solve the eqn of type (Ax=kBx). size of the matrices are 168x168, i am getting 'info' as 170 when i make the run - understand that this should be zero..could some one explain physical meaning of 'info' not equal to zero.. i went through the online manual (http://www.nag.co.uk/numeric/fl/manual/pdf/F08/f08...), but it is still not clear to me.
thanks for your time,

The number of the Info gives you some hint on what the error might be
If Info = 0 => then all OK, no error
