In case this is interesting to others, I currently have the following 
display in pure .m, which is good but for the indenting:

>> C
C =
{
  [1,1] =  1
[2,1] = (sym) x
[3,1] = (symfun) f(x)
  [1,2] =  2
  [2,2] =
  {
    [1,1] =  42
[1,2] = (sym) x
[1,3] = (sym) 2⋅x
    [1,4] =  42
  }
[3,2] = (sym 2×2 matrix)
  ⎡1  x⎤
  ⎢    ⎥
  ⎢   π⎥
  ⎢x  ─⎥
  ⎣   2⎦
}


and of course this would be nicer:

>> C
C =
{
  [1,1] =  1
  [2,1] = (sym) x
  [3,1] = (symfun) f(x)
  [1,2] =  2
  [2,2] =
  {
    [1,1] =  42
    [1,2] = (sym) x
    [1,3] = (sym) 2⋅x
    [1,4] =  42
  }
  [3,2] = (sym 2×2 matrix)
    ⎡1  x⎤
    ⎢    ⎥
    ⎢   π⎥
    ⎢x  ─⎥
    ⎣   2⎦
}
