euler method with more than one step value in matlab

main.m
function [t, y] = eulerMethod(f, a, b, y0, h)
    % f is the differential equation function
    % a and b are the start and end values of the independent variable
    % y0 is the initial value of the dependent variable
    % h is the step size

    % Calculate the number of steps
    n = floor((b - a) / h);

    % Initialize arrays
    t = zeros(n+1, 1);
    y = zeros(n+1, 1);

    % Set initial values
    t(1) = a;
    y(1) = y0;

    % Euler's method iteration
    for i = 1:n
        t(i+1) = t(i) + h;
        y(i+1) = y(i) + h * f(t(i), y(i));
    end
end
