Singular Manual: tensor

  | ### 5.1.157 tensor `Syntax:` `tensor (` matrix_expression `,` matrix_expression `)` `tensor (` module_expression `,` module_expression `)` `tensor (` smatrix_expression `,` smatrix_expression `)` `Type:` same as the first argument `Purpose:` computes the tensor product (Kronecker product) of A and B `Example:`
        ring r=32003,(x,y,z),(c,ds);
        matrix A[3][3]=1,2,3,4,5,6,7,8,9;
        matrix B[2][2]=x,y,0,z;
        print(A);
      ==> 1,2,3,
      ==> 4,5,6,
      ==> 7,8,9
        print(B);
      ==> x,y,
      ==> 0,z
        print(tensor(A,B));
      ==> x, y, 2x,2y,3x,3y,
      ==> 0, z, 0, 2z,0, 3z,
      ==> 4x,4y,5x,5y,6x,6y,
      ==> 0, 4z,0, 5z,0, 6z,
      ==> 7x,7y,8x,8y,9x,9y,
      ==> 0, 7z,0, 8z,0, 9z
