I'm relatively new to matlab and would appreciate some advice on how to use the for loop function.
What I want to accomplish: create a variable including the numerical values solved by a simple equation in a loop. The math is pretty simple- forward euler method- but I don't know how I would set this up in a loop- if that's even possible. (I know this can be done in excel... So I imagine it can be done in matlab...)
Variables: CFC0 %initial value of CFC; given (2.9e11) dt=3.5 k=35
In essence, this is what I want (29 times):
CFC1= cfc0 +k*cfc0*dt;
CFC2= CFC1 +k*CFC1*dt;
CFC3= CFC2 +k*CFC2*dt;
But I want all of the CFC outputs to be organized into a column (or row) of a new variable CFC_100.
I don't know how to start this, and would be grateful for any hints!

(You might want to double check the equations for forward euler, but I gave you help on for loops below, since that is what you asked.)

Here is a hint on using for loops:
x(1)=1;
for index=1:10
x(index+1)=x(index)+x(index)*10;
end
disp(x)
You'll obviously need to change some of this code, but that is how you will learn!
