When you say "matrix" for terminals, is it a numeric array with only numbers, or a cell array including 'TP' or whatever code there is at the beginning of each line?

fid = fopen('file.txt');
line1 = fgetl(fid);
res={line1};
while ischar(line1)
line1 = fgetl(fid);
res{end+1} =line1
end
fclose(fid);
res(end)=[]
idx1=find(cellfun(@(x) isequal(x,'DATA MATRIX'),res));
idx2=find(cellfun(@(x) isequal(x,'DATA TERMINALS'),res));
A=res(idx1+1:idx2-2)
B=res(idx2+1:end-1)
