Of course you can do it with using for loop and if statement. But MATLAB can do it much better way like this:
x = rand(480, 1);
x = sort(x); % column vector with 480 values
idx = find(x > 0.9, 1); % smallest index such that x > 0.9
If you want to use for loop and if statement, the code becomes much longer, such as:
x = rand(480, 1);
x = sort(x); % column vector with 480 values
for kk = 1:480
if x(kk) > 0.9
idx = kk; % smallest index such that x > 0.9
break;
end
end
