nicely print out a matrix in mathematica

Question

I have a list of lists (matrix) in mathematica. I want to print it out nicely, with the max in every row in bold. How to do this?

Or maybe even further, with a circle outside such max, is this possible?

Answer 1

You can use MatrixForm to print out matrices nicely:

data = RandomInteger[100, {5, 5}];

data // MatrixForm

yields

You can draw a circle around the maximum in each row as follows:

Map[# /. m : Max[#] :> Framed[m, RoundingRadius -> 1000]  &, data] //
  MatrixForm

yielding

RoundingRadius -> 1000 uses a ridiculously large parameter to get circles. You may need to adjust the constant depending upon the scale of your display.

You can change Framed[m...] with Style[m, Bold] if you prefer bolding.
