understanding some special script from gnuradio

[Markus Feldmann]

Hi All,

to understand my other post named <calculate SNR and watch a binary 
file>, i want to understand a special octave script first.

This script converts a binary file to a complex float numbers
containing I and Q values.
As i think this binary includes I and Q values and print them outs,
like this:
...
   24 +  5i
    1 + 24i
  -23 + 10i
  -19 - 18i
    9 - 24i
   24 +  1i
    5 + 23i
  -21 + 13i
  -21 - 15i
...

Here comes the script:
################################################################
function v = read_complex_binary (filename, count)

  %% usage: read_complex_binary (filename, [count])
  %%
  %%  open filename and return the contents as a column vector,
  %%  treating them as 32 bit complex numbers
  %%

  m = nargchk (1,2,nargin);
  if (m)
    usage (m);
  end

  if (nargin < 2)
    count = Inf;
  end

  f = fopen (filename, 'rb');
  if (f < 0)
    v = 0;
  else
    t = fread (f, [2, count], 'float');
    fclose (f);
    v = t(1,:) + t(2,:)*i;
    [r, c] = size (v);
    v = reshape (v, c, r);
  end
################################################################


Contains each line from the output 2 float numbers ?
Whereas every float is 32 bit ?
So i assume one line includes I + Q ?
