MATLAB: Write a for loop to round up vector

Question

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

Answer 1

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
