function c_595(~,~,~,~,~,~,~,~)
clear,clc
rho = 4000;
c = 500;
k = 10;
L = 20;
T1 = 0;
T2 = 100;
q_gen = 2*10^7;
dt = 5;
Fo = (k*dt)/(rho*c*(0.01)^2);
gen = (q_gen*dt)/(rho*c);
n = 8;
T = zeros(1,n)';
for p = 1:n
T(p) = (Fo*((T1+273.15)+(T2+273.15)) + (323.15)*(1-2*(Fo)) + gen) - 273.15;
end
T
I get a matrix with the value of T, but I want to get a matrix with the fisrt value of T, then that value + second value, and so on. I can't find a way to do it.

Your question is not clear. Please give an example for expected vector for T. Also your loop doesn't make any sense, all elements of T are the same (what's the use of counter p within this loop?)

Ran in:
It sounds like you're describing a cumulative sum which does not need to be done within a loop.
t = [100;100;100;100]
t = 4×1
100 100 100 100
ts = cumsum(t)
ts = 4×1
100 200 300 400
If this is not what you're looking for, please elaborate or provide an explicit example.
