Notation problem: Defining an equation using parenthesis.

Hi all,

I am having the following problem and I'm not sure it has a solution:

I am running the following equations within a 'for loop'.

    Wf = [];
    for i = 1:29         
    Wf = [Wf,SFC*T*(disp(i)/V1)];
    W1(i+1) = W1(i)-Wf(i);
    end

I have defined Wf(i) using parenthesis and I want to know if there is a way I can define W1(i+1) in the same manner.

Thanks in advance

Well sure, you did it already. You just need to make sure that Wf(1) - the first element - has been defined before you assign Wf(i+1).

However I am worried about disp(i). It seems you are using an array call disp that somehow gets assigned before the loop. disp is a built-in function so it's a very bad idea to use a variable with the same name as any built-in function.

Thanks that's a good tip I'll be sure to change it. But I need to define 'W1' not 'Wf' in parenthesis form and I'm confused how to do that when I'm working with W1(i+1)
