Selectively setting significant digits in display

Hi, My program outputs a 2-column array of numbers. I wish to display the first column numbers with the precision of 2 decimal places. However, I want the second column to be displayed with a 9 decimal precision. May someone please suggest the way to do this?

Thanks.

Make use of fprintf.

Here's a short example:

% Create 2-column array of random numbers (0 - 1)
num = rand(10, 2);

% Make some values greater than 10 or 100
num(10) = num(10)+10;
num(15) = num(15)+100;

% Display with specified number of digits
%   Note: transpose "num".
fprintf('%6.2f  %13.9f\n', num');

This displays:

    0.91    0.494173937
    0.80    0.779051723
    0.10    0.715037078
    0.26    0.903720561
    0.34  100.890922504
    0.68    0.334163053
    0.14    0.698745832
    0.72    0.197809827
    0.11    0.030540946
   10.65    0.744074260
