This is a simple question... but couldn't find the answer. I am trying to solve some symbolic matrix equations. Take a==b.c where a is 2x1 unknowns b \!\(\*FormBox[ RowBox[{"b", "=", RowBox[{"(", GridBox[{ {"1", "2"}, {"3", "4"} }], ")"}]}], TraditionalForm]\) and c us 2x1 unknown. Is it possible to tell mathematica that a and c are matrix variables? and have a statement SolveEquation[a == b.c, c[[1]]]. with out putting variables in each of the matrix elements as in \!\(\*FormBox[ RowBox[{"a", "=", RowBox[{"(", GridBox[{ {"x"}, {"y"} }], ")"}]}], TraditionalForm]\) \!\(\*FormBox[ RowBox[{"c", "=", RowBox[{"(", GridBox[{ {"e"}, {"f"} }], ")"}]}], TraditionalForm]\) , SolveEquation[a == b.c, e]. Thanks
