Different precision inside matrix

I'm creating an engineering program which calculates reaction forces and
deformations in trusses. The calculation method works basically with
matrices. The final result is also shown in matrices. My problem, though, is
that I want to display the elements of the results' matrix with different
precisions. It'd be something like: 

A = [ 1  4590.66  0.005493; 
        2  4983.89  0.0393837584];

I've tried to use the command "output_precision()", but it changes all the
elements' precision. The command "format free" doesn't work either, because
it displays the matrix like this:

A = [1  4590.6693848574 0.005493848748;
       2  4983.89948         3.9383758432e-002];

Is it possible to define a specific precision for each element of a matrix?
