How to display matrix with n digits in each cells?

Hi, I would like to know how to display a matrix with 3 digits in each cells. Not 4, not 2, 3 digits. Even if the value is zero, I want 0.00. If the value is 0.02, I need to have 2.00e-2.

I tried matrice_Q=round(Q,3,'significant'), and it doesn't work.

if true
Sr=matriceS(propmeca.verrepox,1);% This is a function who calls a matrix.
Sr =
 1.0e-03 *
 0.020000000000000  -0.005080000000000                   0
-0.005080000000000   0.065789473684211                   0
                 0                   0   0.212765957446809
format shorteng
matrice_S=round(Sr,3,'significant')% 3 chiffres significatifs

 And I get:
matrice_S =
    20.0000e-006    -5.0800e-006     0.0000e+000
    -5.0800e-006    65.8000e-006     0.0000e+000
     0.0000e+000     0.0000e+000   213.0000e-006
end

How do I get rid of the zeros after the first 3 digits? I don't need precision, I need to display only 3 digits. Matlab won't use these results for further calculations.

if true
I need:
matrice_S =
  20.0e-006    -5.08e-006     0.00e+000
 -5.08e-006     65.8e-006     0.00e+000
  0.00e+000     0.00e+000     213e-006
end

I want my matrix to look like this, straight, well placed, all lined up, and with the right number of digits. Could some body help me please?

Thanks! :)

   disp(num2str(Sr, '%.2e '))

It works! Thanks!!
