Hi Rodriguez,
To read your A.m file, you can use this..
Data = textread('A.m', '%s', 'delimiter', '');
All data of file A.m will be stored into variable ' Data'
you can read and edit the data in variable ' Data' line by line as follows:
for i=1:length(Data)
lineData = Data{i};
lineData = strrep(lineData,'ABC','XYZ');
newData{i} = lineData;
end
then you can write the newData into A.m file as follows:
fid = fopen('A.m','w');
for i=1:length(newData)
fprintf(fid,'%s\n',newData{i});
end
fclose(fid);
