In quantum physics one often needs the matrix representation of tensor products Outer[Times,{{1,2},{3,4}},{{a,b},{c,d}}]//MatrixForm outputs something like this: {{{{a,b},{c,d}},{{2a,2b},{2c,2d}},{{{3a,3b},{3c,3d}},{{4a,4b},{4c,4d}}}} what I need is {{a,b,2a,2b},{c,d,2c,2d},{3a,3b,4a,4b},{3c,3d,4c,4d}} How to get this? Thanks in advance ahautot at ulg.ac.be
