[GAP Forum] how to do matrix multiplication of polynomial for input as ideal after load singular package

[Lee Martin CCNP]

Hi,
LoadPackage("singular");onelist := Tuples([0,1,0,1,0,1],3);onelist2 := 
[];Append( onelist2, onelist );Append( onelist2, onelist );Append( onelist2, 
onelist );matrixlist := Tuples(onelist2,3);
R1:= PolynomialRing( Rationals, ["x","y","z"] : new 
);;x:=IndeterminatesOfPolynomialRing(R1)[1];y:=IndeterminatesOfPolynomialRing(R1)[2];z:=IndeterminatesOfPolynomialRing(R1)[3];
hello:=Matrix([[x,y,z]])*Matrix(matrixlist[1]);  <- got error at here
Regards,
Martin
