For loop comand use

Hi,I want to compute the sum 2 + 4 + 6 + 8 + 10 + : : : + 100 by using For loop . Can anyone here thankfully help me out?

What have you done so far? What specific problems are you having with your code?

[F.O]

Actually I am asked to do the sum in to ways and the second one is For loop which i dont understand first way is

a=sum([2:2:100])

I tried the way you recommended but get nothing when i run it except that i get

   k=100
  total=50

total = 0;
for k=2:2:100; 
    total = total + 1; 
end

Change

total = total + 1;

to

total = total + k;  % <-- You need to add the index variable k, not 1 every time

I have changed it and got correct answer. Thanks

The general outline of your for loop would be:

total = 0;
for k=start_value:increment:end_value  % <-- you fill in the start_value, increment, and end_value
    total = total + something;  % <-- you fill in the something
end
