No, the way I wrote the for loops is to step through a range of values in 
a given increment.

If you want a non linear range, I suggest you create an array of values 
and use a foreach loop to step through the array. Note that in this 
example I'm also using 3 digit orient and freq in the file names, and 
I've reduced the code inside the loop to a single statement (that will 
wrap because of usenet limitations).

example:

$orients = array(30, 28, 42, 98); // all the orient vals
$freqs = array(.30, .38, .37, .41); // all the freq vals
foreach ($orients as $o)
    foreach ($freqs as $f)
        make_gabor($o, $f, sprintf("gabor_patches/patch_%03d_%03d.png", 
$o, $f * 100));
