HESSIANMThis record contains the Hessian matrix. The ordering is $F_{1x1x}, F_{1x1y}, F_{1x1z}, F_{1x2x} \cdots F_{nx1x}, F_{nx1y} \cdots$. Atoms follow the computational order. The record is written by xvdint and xcphf. Data type: integer. Dimension: 9*NATOMS*NATOMS. Written by: see above. For variable definition see: Terms of reference. |
