Writing for loop with a intial value given

I have 35 different values of udotreal I have initial value of u I want to write a for loop to get 35 values of u by doing this: New value of u = previous value + corresponding udotreal value. I was trying something like this:

for i = 1:35 u(1,i) = u(1,i) + udotreal(1,i);

end

Please help. Thanks in advanced

Start your for-loop at 2, and use the previous value (i-1) to get the new one:

u(1) = ...
for i=2:35
   u(i) = u(i-1) + udotreal(i) ; % or udotreal(i-1), I am not sure what you mean
end

This is what I want to do;

uk1 = uk + udotreal(1,1);

uk2 = uk1 + udotreal(1,2);

uk3 = uk2 + udotreal(1,3);

uk4 = uk3 + udotreal(1,4);

uk5 = uk4 + udotreal(1,5);

uk6 = uk5 + udotreal(1,6);

and so on...

do not create variables named like this! It is the contents of a variable that should be flexible, not its name.

The code above does what you suggest, storing all subsequent values into a single variable, but at subsequent locations, in the variable u. You have to define u(1) though.

Thank you. I got my code working using if else statement.

I have the variable named like that since I have more than 50-60 variables in the entire code and this is just a small part of the code. Hence, it seems to be a weird variable name.
