This command allows for the scalar multiplication of an NCMatrix by an NCRingElement on the left.
i1 : B = threeDimSklyanin(QQ,{1,1,-1},{x,y,z}) --Calling Bergman for NCGB calculation. Complete! o1 = B o1 : NCQuotientRing |
i2 : M = ncMatrix {{x, y, z}} o2 = | x y z | o2 : NCMatrix |
i3 : sigma = ncMap(B,B,{y,z,x}) o3 = NCRingMap B <--- B o3 : NCRingMap |
i4 : N = ncMatrix {{M},{sigma M}, {sigma sigma M}} o4 = | x y z | | y z x | | z x y | o4 : NCMatrix |
i5 : x^2*N o5 = | x^3 x^2*y x^2*z | | x^2*y x^2*z x^3 | | x^2*z x^3 x^2*y | o5 : NCMatrix |
