Im trying to find out how to take out a number that's above 10 in a vector of v=[-5, 2, -4, 1; 0, -9, -9, 20; 50, 89, 99, 100] using for loop and using user defined functions

without loop (efficient)
v=[-5, 2, -4, 1; 0, -9, -9, 20; 50, 89, 99, 100]
result = numbergreaterthan10(v) %function calling
function result = numbergreaterthan10(x) %function definition
result= x(x>10);
end
with loop (not efficient)
v=[-5, 2, -4, 1; 0, -9, -9, 20; 50, 89, 99, 100]
result = numbergreaterthan10(v) %function calling
function result = numbergreaterthan10(x) %function definition
for i = 1:numel(x)
if x(i)>10
result(i)=x(i);
else
continue
end
end
result=nonzeros(result);
end
