Is there a way to display only specific columns of a matrix (say columns 1, 10, 20, 32) with column and row headers for display purposes?

Hint:

    M = magic(12);
    M( :, [ 3, 5 ,9 ] )

returns

    ans =
         3   140   136
       130    17    21
       118    29    33
        39   104   100
       ....

and see fprintf
