correct my Postprocessing code

Hi,

I am trying to get 3 surface graph from my output results of Matlab. The postprocessing code is always showing me an error when using str2num.

here you will find the inp and out file which will be asked by post-processing file.

please find out my wrong

the error comes like this one ??? Error TMP = str2num(fgets(INP2));

input http://download1081.mediafire.com/0oid776oj1kg/oxikjw05p5lu3jg/50.inp

output http://199.91.152.42/hgmyxm3u6bug/k6cg69lo4tdgigx/50strs.out

post-processor.m http://199.91.153.194/r5386ugkl7fg/bpqd6uhuvjauwmj/Postprossing.m

Change your line

TMP = str2num(fgets(INP2));

to

thisline = fgets(INP2);
if ~ischar(thisline)
  error('Ran out of input, or serious input error')
end
try
  TMP = str2num(thisline);
catch
  error(['Substantial input error trying to understand line: ', thisline]);
end
if any(isnan(TMP))
  warning(['Line could not be interpreted as numbers: ' thisline]);
end

I have not looked at the program itself, but I note that if it ever got as far as the input line

Elem#   N1   N2   N3   N4   Mat#   Thickness   TempRise

then it would run in to trouble. I would not expect an error to be generated though.

Check the help of fgets(). Maybe you want to try fgetl()?
