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.

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.
