this is my code:
results = '';
for i = 1 : 1 : length(BBArray)
results = results + sprintf('%.0f\t' , BBArray(i, :))+'\n';
results + sprintf('%.0f\t' , BBArray(i, :))+'\n';
end
results;
how can i improve?

What do you want to do with this code? You want to concatenate each row of the matrix to results??

You cannot use + to concatenate character vectors.
If you are using R2017a or later, you could change the initial
results = '';
to
results = "";
and that would have you working with string objects instead of character vectors, which would support using + for concatenation.
