I think Simplify does work on arrays. In any case, you could always Map Simplify to level {2} of your matrix expression. Map[Simplify, matrix, {2}] But simplifing expressions to the form that you want is something of an art. It may be difficult to write a single Simplify command that works the way you want on all elements of the matrix. You may have to combine Simplify with some Rules that perform specific transformations. You may have to use MapAt to transform specific matrix elements. Without seeing your actual matrix expression it is difficult to be more specific. Giving specific examples on MathGroup will almost always elicit a better response.

Every expression is long and therefore it is difficult to analisys. I know, there is Simplify[] function but it doesn't work when its parameter is matrix or vector. How can I simplify all elements within this matrix ? -- Regards CYSTERNA++
