Solving equation using for loop

Iteratively compute Vm. Starting with 0 , use a for-loop

to iterate through all time steps.

I am getting error in solving this. Am I solving this correctly?

clear all;
clc;
rm=0.9;
V(0)=0;
cm=12;
Tm=10.8;
t=0:0.05:250;
ie=25;
for i=1:length(t)-1
    dV(i)=(1/Tm)*(rm*ie -V(i-1))*dt;
     V(i+1) = V(i)+dV(i);
end

Your code throws (as expected from reading it):

Array indices must be positive integers or logical values.
V(0)=0;

MATLAB subscript indexing uses only integers greater than zero. You need to revise your code so that none of the subscripts are negative or zero.

Array indices must be positive integers or logical values.

Please see my Answer!

I already explained the reason your code is throwing that error, and what you need to do to correct your code.
