MATLAB: For loop Stoping after saving

for loop

In my program I created a for loop that goes through different parameter values for processing an image and at the end it saves each image with the different parameter value. The only problem is that it only goes through the first iteration. 1. program load all paramater values 2. for loop
for JitterAmp = 0:0.33:0.66
  for TarScale = 0.001:0.100:1
 % does all calculations
 % saves all images 
if Nbits > 16
   fname = [nameString, '.raw']
end
cd(oldfolder);  % this contains the pathname where file is to be saved
   % it then simData with bit numbers
  if Nbits > 16
     writeSimData (oldfolder, fName, uint32(F5));
end 
end
end
The program works for only the first iteration where JitterAmp is 0 and tarScale is 0.001. After it saves it , the program stops. What can I do?

You'll just have to step through it line by line to find out where it gets kicked out of the for loop, because that code looks fine to me.

Regarding your for loop values, you'd also better have a look at the FAQ: https://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F If you don't fully understand that (which it appears that you don't) then you'll run into trouble.
