Dear Matlaber,

I have a bunch of output files in the folowing format X.0.ii.out where .ii goes from 00 to 40 with an increament of 01.

I would like to upload these files on matlab and conduct a search task. I am looking for a matrix of 3x3 after a line starting with 'total stress'. This lines appear at multiple occasion in the output file and I just need the last matrix. The code is below

fmt1='total stress%n';
fmt2=['(' repmat('%f',1,3) ')'];
flds={'X','Y','Z'};
fid=fopen(X*.out,'r');
dat=struct([]);
i=0;
while ~feof(fid)
  i=i+1;
  dat(i).m=cell2mat(textscan(fid,fmt1,1));
  for j=1:length(flds)
    dat(i).(flds{j})=cell2mat(textscan(fid,fmt2,3,'collectoutput',1)).';
  end
end
fid=fclose(fid);

this one does not work as X*.out is not a calid syntax in matlab an it gives all the 3x3 matrix in the file.

any idea how to solve this?

After correcting

d=dir('X*.out')

this gives an error for

fopen(d(i).name,'r')

Subscript indices must either be real positive integers or logicals.

'Cuz I automatically write 'i' for indices and you'd already used it so I wrote 'f' for the for loop index but see beginning of sentence...fix the subscript to match the loop variable.
