About the nodes sequence in the global stiffness and mass matrix

Dear all,

Hi. When I got the stiffness and mass matrix using the 'mphmatrix' with matlab, and got the nodes and elements sequence of the model from DATA.vertex and DATA.elem using '[STATS,DATA]=mphmeshstats(model)', I found that the sequence of nodes corresponding to each row in the stiffness or mass matrix is not consistent with the sequence of nodes in DATA.vertex. For example, the third row in the stiffness may be not corresponding to the third node in the DATA.vertex. So my question is what is the sequence of nodes in the matrix?

I appreciate your help,

Regards, Yexi
