[GAP Forum] OrderMat(m)

[Nasira Sindhu]

Dear Forum,

i have a Problem with the function OrderMat. 
It doenst work on my PC (wind. vista).
Should I install an extra Package for this function? 

I enter the following example (from the manual 34.11):
 gap> OrderMat( [ [ 0*Z(2), 0*Z(2), Z(2)^0 ],
    >                 [ Z(2)^0, Z(2)^0, 0*Z(2) ],
    >                 [ Z(2)^0, 0*Z(2), 0*Z(2) ] ] );

but I get : Variable: 'OrderMat' must have a value

best regards
nasira
