ZZ * NCMatrix -- Product of NCMatrices

Synopsis

This command allows for the scaling of an NCMatrix by an element in ZZ.

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 : 3*N

o5 = | 3*x 3*y 3*z |
     | 3*y 3*z 3*x |
     | 3*z 3*x 3*y |
