Hey everyone I have multiple files by the name of outputfile0001.txt, outputfile0002.txt ... upto outputfile0060.txt . each file has a structure like this:
- 0.26630448E-08 0.62768422E+00
- 0.30589992E-08 0.64235565E+00
- 0.35138231E-08 0.65737000E+00
- 0.40362683E-08 0.67273529E+00
- . .
- . .and so on.basically two sets of numeric arrays gi(i) and rri(i)are there in these files.Now what i want is to is from each file plot(rri(),gi()).Any help is appreciated.I tried the code below with error that:'error in opening file'
numfiles = 60; mydata = cell(1, numfiles);
for k = 1:numfiles myfilename = sprintf('outputfinal%d.txt', k); mydata{k} = importdata(myfilename); end

myfilename = sprintf('outputfinal%d.txt', k)
will produce e.g.
outputfinal1.txt
To get the zeros in the filename, use
myfilename = sprintf('outputfinal%04d.txt',k)
Best regards, Michael

I mean, if you write the code line I have provided in the previous comment in your loop, before the importdata line. Then fid will have a value. -1 indicates that it cannot find the file, any other value (>2) indicates that the file can be accessed. Instead, you could also write
dir(fullNameWithPath)
to check if Matlab really finds the file.
