Error using + Matrix dimensions must agree.

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.
