function y_prime = euler_method(x, y, y_prime)
h = 0.1; % 步长
x_values = 0:h:3;
for i=1:length(x_values)-1
y_double_prime = -3*y_prime - 2*y; % 根据微分方程求解y''
y = y + h * y_prime; % 更新y
y_prime = y_prime + h * (y_double_prime); % 更新y'
end
end
% 初始条件
x_0 = 0;
y_0 = 2;
y_1prime_0=1;
% 调用函数并输出结果
result=euler_method(x_0,y_0,y_1prime);
disp(result);
