dynamic format specifiers

[Bart Vandewoestyne]

Hello list,

Consider the following code for writing out a matrix with 3
columns:

  A = rand(10,3);
  printf('%g %g %g\n', A');

Now in my application, I dont know the number of columns of A in
advance.  So I have something like:

  A = rand(10,k);

where k can be any value.

The problem that then arises, is that the format string with the
'%g' changes at run time.

How do i change my printf statement so that it works with any
number of columns of A?

Thanks,
Bart
