Reading text file coordinate point

Hi

Right now I have a simple text file with a single coordinate point (0.2, 0.8, 0.5) and I would like to read it into MATLAB so that I have 3 variables x = 0.2, y = 0.8, z = 0.5.

importdata will only give me 1 value, which looks like (0.2, 0.8, 0.5) and when I tried using textscan(fileID, '%d'), I just get one value which looks like [].

What do I need to put, please help! Thanks

Please show us an exact copy of one of the text files.

Well it just has this in the top left hand corner and that is all.

(0.3, 2.8, 0.2)

"...I tried using textscan(fileID, '%d')"

(0.2, 0.8, 0.5) values are floating point, not integers so %d won't work and you didn't account for the nonnumeric paren's nor the delimiter in the format string...

   >> s='(0.2, 0.8, 0.5)'
  s =
  (0.2, 0.8, 0.5)
  >> textscan(s,'(%f%f%f)','delimiter',',','collectoutput',1)
  ans = 
      [1x3 double]
  >> cell2mat(textscan(s,'(%f%f%f)','delimiter',',','collectoutput',1))
  ans =
      0.2000    0.8000    0.5000
  >>

NB the collectoutput parameter as well as delimiter. I also went ahead and wrapped the call w/ cell2mat to get a "regular" array rather than a cell array that is returned by textscan
