Can someone help me convert this if-else statement to a switch statement? Its a homework problem that requires us to answer whether it would be quicker to write it as a switch or as an if-else statement. Im most confused by the for loop at the top.

for i = 1:2000 
for j = 1:6 
if j == 1 
result = 20; 
elseif j == 2 
result = 30; 
elseif j == 3 
result = 40; 
elseif j == 4 
result = 50; 
elseif j==5 
result = 60; 
else result = 0; 
end 
end 
end
