MATLAB: Euler’s method, error, when I run the code i get an error message when trying to create the array for the x values, Array indices must be positive integers or logical values.

Question

clear

clc

close all

t0 = 0;

x0 = 3;

tf = 1;

n = 10;

tArray = linspace(t0, tf, n+1);

xArray = [x0];

h = (tf – t0)/n;

%————————–variables————————

%function for diffrential equation

f =@ (t,x) -3*t*x;

for ii = h : n

x = x0 + h * f(t0,x0);

t = (t0 + h);

x0 = x;

t0 = t;

xArray(ii+1) = x0

end

disp (xArray)

disp(tArray)

Answer 1

Change

for ii = h : n   

to

for ii = 1 : n
