You can use xlsread function if you have the data in the form of excel or csv.
Let us take a as the variable holding data.
[m n] = size(a);
num_rows_NaN = 0;
num_rows_number = 0;
for i = 1:m
if (sum(isnan(a(i,:)))) == 0
num_rows_NaN = num_rows_NaN + 1;
else
num_rows_number = num_rows_number + 1;
end
end
