i have a vector = [123.231 232.123 123.565 123.543] I need to use for loop to give out an result as:
number 1 is 123.2 number 2 is 232.1 number 3 is 123.6 number 4 is 123.5
which is round up to 1 decimal place.
Here I got:
vec = [1.111 2.222 3.222 4.222];
for i=1:length(vec)
fprintf('Element %d is %5.1f \n',i,vec)
end
I cant see what's wrong with my code but it wasnt display want i need. Could anyone help me out? Thanks

you forget to use vec(i) instead of vec
vec = [1.111 2.222 3.222 4.222];
for i=1:length(vec)
fprintf('Element %d is %5.1f \n',i,vec(i))
end
