i have to write parameters into a .txt file where there are already some written lines (a sort of template) like this
from:
Dictionary kinetics
{
@Kinetics
@Thermodynamics
@Output
}
to:
Dictionary kinetics
{
@Kinetics Cartel1;
@Thermodynamics Cartel2;
@Output Cartel3;
}
the number of whitespaces in beetween isnt a problem, I can' t find a way to do it

Try this
% Open the file for reading in text mode.
fileID = fopen(fullFileName, 'rt');
% Open the file for reading in text mode.
outputFileID = fopen(outputFullFileName, 'wt');
% Read the first line of the file.
textLine = fgetl(fileID);
lineCounter = 1;
while ischar(textLine)
% Print out what line we're operating on.
fprintf('%s\n', textLine);
if contains(textLine, 'Kinetics')
textLineOut = sprintf('%s %f', textLine, Cartel(1))
elseif contains(textLine, 'Thermodynamics')
textLineOut = sprintf('%s %f', textLine, Cartel(2))
elseif contains(textLine, 'Output')
textLineOut = sprintf('%s %f', textLine, Cartel(3))
end
% Output line of text to output file
fprintf(outputFileID, '%s\n', textLineOut);
% Read the next line.
textLine = fgetl(fileID);
lineCounter = lineCounter + 1;
end
% All done reading all lines, so close the files.
fclose(fileID);
fclose(outputFileID);
Untested, so adapt as needed.
