Code gives Loop function error

Hello friends,

Trying to write code for a FEM model, stuck on loop function. Basically want to write a simple function first where F(t) = 500 at t=0 and decreases as a linear function in increments of dt=0.1, to be F(t) =0 at t=0.5. I'll then use these F0, F1,... values for further calculations. Can you please advise where am I going wrong?

Ta!

Error in 5514 (line 25)

F(i+1)=F(i)-100;

clear all;
close all;
clc;

F0=500;

for i=0:0.1:0.5;
    
    F(i+1)=F(i)-100;
    if F(i+1)<=0;
        break
    end

end

t = 0:0.1:0.5;
F = 500 - 1000*t;

Hi Torsten,

I need all 5 instances of F i.e. F1 thru F5, That's why I have used as F(i+1) = F(i)-100*i; I want the code to find the value of F based on previous value. Thoughts?

[Torsten]

F(1) = 500;
for i = 1:5
   F(i+1) = F(i) - 100;
end
