hi folks,
the file i've got has this format:
DATA
PIPE MEDIUM | MASS-FLOW MOLE-FLOW VOL-FLOW | PRESSURE
NO TYPE | [kg/s] [kmol/s] [m3/s] | [bar]
1 GASMIX | 0.00156 0.00005 0.00085 | 1.0000
| 0.00085 | 1.0000
2 GASMIX | 0.00156 0.00005 0.00415 | 1.0000
| 0.00415 | 1.0000
3 GASMIX | 0.00178 0.00007 0.00927 | 1.0000
VOLTAGE/CELL = 0.8000 [V]
CURRENT DENSITY = 3504.80 [A/m2]
DC-POWER = 1.6748 [kW]
AC-POWER = 1.5074 [kW]
i need to read the values of massflow of pipe nr.1 and of the ac-power. after that i need to save the values in a table after each run.
any ideas? thanks cyros

fid = fopen('file.txt');
str={};
while ~feof(fid)
str{end+1,1}=regexp(fgetl(fid),'(?<= \|).+(?=\|)','match')
end
fclose(fid);
str(cellfun(@isempty,str))=[]
str=str(3:end)
str=str(1:2:end)
a=cell2mat(cellfun(@(x) str2num(x{1}),str,'un',0))
out=a(:,1)
