user defined functions help

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

[KALYAN ACHARJYA]

No need of for loop? Is it must to used?

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
