[molpro-user] Lagrangian multipliers in CC code

Dear Molpro users and developers,

Dear Werner

Thanks for the quick response. I realize MOLPRO stores solutions of the CPHF equations whenever a relaxed CC properties calculation is requested as in:

{ccsd
      core, 0
      expec, relaxed, dm
}

Indeed, the output file reports:

Solve  a set of linear equations for Lambda...
Saving Lambda vector on record 4499.8

However, I haven't been able to access this record successfully using the MATROP directive. Do you know how to actually print the contents of this binary record in the output file? 

Best regards

Rodrigo
