Hi everyone, I'll explain my problem.
I have two arrays of the same length which are called respectively: target_2019 and output_2019, what I am going to do is the difference between these two arrays and I calculate the MAPE. However, some of the values ​​present in target_2019 are zeros, how can I eliminate these zeros by simultaneously eliminating the measure that corresponds to this zero in the output_2019 array?
I hope I was clear.
Would anyone know how to help me?

How can I calculate the MAPE? If I divide the two arrays, I get a matrix

idx_to_remove = target_2019==0;
target_2019(idx_to_remove) = [];
output_2019(idx_to_remove) = [];
