hello Carolina
this code will scan the file and search for the targeted variables
you can expand (add more variables) if you wish
it will retrieve associated numerical data , whatever the dimensions (width) of the data
hope it helps
Filename = 'Case_1.txt';
fid = fopen(Filename);
tline = fgetl(fid);
while ischar(tline)
if contains(tline,'Engine Speed :')
tmp = strtrim(regexp(tline, '\s+', 'split')); %split by spaces
dd = regexp(tmp,'-?[0-9]+.[0-9]+', 'match'); % extract numeric parts only inside the cell (in case of mix with text)
str_temp = strjoin( cat(2,dd{:}), ',') ; % Transform a cell array of cell arrays into string / delimiter = blank or comma
Engine_Speed = str2num(str_temp); % convert string to num
end
if contains(tline,'BMEP [bar]')
tmp = strtrim(regexp(tline, '\s+', 'split')); %split by spaces
dd = regexp(tmp,'-?[0-9]+.[0-9]+', 'match'); % extract numeric parts only inside the cell (in case of mix with text)
str_temp = strjoin( cat(2,dd{:}), ',') ; % Transform a cell array of cell arrays into string / delimiter = blank or comma
BMEP = str2num(str_temp); % convert string to num
end
if contains(tline,'BSFC [g/kWh]')
tmp = strtrim(regexp(tline, '\s+', 'split')); %split by spaces
dd = regexp(tmp,'-?[0-9]+.[0-9]+', 'match'); % extract numeric parts only inside the cell (in case of mix with text)
str_temp = strjoin( cat(2,dd{:}), ',') ; % Transform a cell array of cell arrays into string / delimiter = blank or comma
BSFC = str2num(str_temp); % convert string to num
end
tline = fgetl(fid);
end
fclose(fid);
