Re: Editing .txt file in Octave

[Stefan Neumann]

This seems to work:

--- datafile 'foo.dat' ---
1m
1n
1u

--- script 'dats.m' ---
infile="foo.dat";
[fid] = fopen(infile, "r") ;
[m, count] = fscanf(fid, '%f%c',[2,3]);
fclose(fid);
m=m';
m
for i=1:size(m(:,2))
  if(m(i,2)==109) m(i,1)*=1e-3; endif
  if(m(i,2)==110) m(i,1)*=1e-9; endif
  if(m(i,2)==117) m(i,1)*=1e-6; endif
endfor
m
vals=m(:,1);
vals

--- this is what happens (chatter deleted) ---
MYPC$ octave dats.m

m =

     1   109
     1   110
     1   117

m =

   1.0000e-03   1.0900e+02
   1.0000e-09   1.1000e+02
   1.0000e-06   1.1700e+02

vals =

   1.0000e-03
   1.0000e-09
   1.0000e-06
