        "diagonal matrix construction"
        SYNTAX: X = dmconstr(n, el)

        n is a positive integer.
        el is an element of Z, Q, Z/mZ, GF(p^n) (where p is a 
        prime), number fields, polynomials over these structures 
        or rational functions over Q.

        X is assigned the nxn - diagonal matrix with el on the 
        diagonal.


        Example 1: (correct)

                dmconstr(4,MOD(3*x+2))
