How to extract the stiffness Matrix for a certain element?

Dear all,

Hi. I need to extract the stiffness Matrix for a certain element or node before assembling. The "mphmatrix" command gives me the results for whole geometry (After assembly). I wonder if there is any way for getting the matrix for certain elements? For example say that element number 2 or ... .

I appreciate your help,

Regards,
