Writing for loop with a intial value given
显示 更早的评论
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

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.
