import textoveho suboru do matlabu

[Michal Lukac]

Nieco podobne som robil, ale som pouzil fciu fget1() naraz nacita cely 
riadok, takze uz len porovnanvat s hlavickou "Frequency"    "Data Trace" 
"Memory Trace" a potom dalsi riadok su uz data.

clear all
fid = fopen('rrr.txt', 'rt');
i=1;
aa=[0 0 0];
tline = fgetl(fid);
while feof(fid) == 0
  matches =strfind(tline,'"Frequency" "Data Trace" "Memory Trace"');
  if ~isempty(matches)
    tline = fgetl(fid);
    while feof(fid) == 0
      aa= textscan(tline,'%f%f%f');
      bb(i,:)=[aa{1} aa{2} aa{3}]
      i=i+1;
      tline = fgetl(fid);
    end
  end
  tline = fgetl(fid);
end

Subject: import textoveho suboru do matlabu


ucim sa v matlabe a neviem rozlusknut znacne trivialnu zalezitost :-) chcem 
naimportovat textovy subor ktory ma hlavicku a potom obsahuje tri stlpce 
ciselnych dat (vid nizsie). Naimportovat subor od zaciatku viem (pouzivam 
textread), ale neviem dojst na to ako odignorovat tu hlavicku... Funkcia 
textscan dokaze robit seek v ramci suboru, ale neviem ako ziskat poziciu 
znaku v subore ktorym sa zacina ciselna cast. Viete mi niekto prosim 
poradit?
dik, b.
