对任意给定正整数N,输出N的阶乘，并计算5的阶乘。分别编写命令式M文件和函数M文件

命令式M文件实现：

N = input("请输入一个正整数N：");
factorial_N = 1;
for i = 1:N
    factorial_N = factorial_N * i;
end
disp("N的阶乘为：" + factorial_N);

factorial_5 = 1;
for i = 1:5
    factorial_5 = factorial_5 * i;
end
disp("5的阶乘为：" + factorial_5);

函数M文件实现：

function [factorial_N, factorial_5] = compute_factorial(N)
% 计算N的阶乘和5的阶乘

factorial_N = 1;
for i = 1:N
    factorial_N = factorial_N * i;
end

factorial_5 = 1;
for i = 1:5
    factorial_5 = factorial_5 * i;
end

end

使用示例：

>> [factorial_N, factorial_5] = compute_factorial(6)
factorial_N =
   720
factorial_5 =
   120
