我试图在Matlab中运行以下Python代码：

                for i in range(p+1):
                    if u+r+i == p:
                        temp.append([u,r,i])

start = time.time()
E_array, tt, kb = main()
end = time.time()
print('runtime: {:.3f}'.format(end-start))
plt.figure()
plt.title('Temperature vs time')
plt.plot(tt*1e3,E_array/kb, linestyle = '', marker = 'o', color='black')
plt.show()

问题是，当我尝试调用py.matcode.main()时，收到以下错误消息：Python错误：

main（）缺少14个必要的位置参数：＆＃39; E_array＆＃39;，＆＃39; k＆＃39;，＆＃39; m＆＃39;，＆＃39; O_sqr＆＃39;，＆＃39; G_sqr＆＃39;，＆＃39; Dl＆＃39;，＆＃39; hb＆＃39;，＆＃39; kb＆＃39;，＆＃39; TD＆＃39;，＆＃39;方法＆＃39;，＆＃39; p_list＆＃39;，＆＃39; o_ho＆＃39;，＆＃39; Ae＆＃39;和＆＃39; p_max＆＃39;

即使Matlab显示Python在运行我的代码时遇到问题，但代码在Python中运行良好。

此外，我我能够致电py.matcode.make_p(py.int(5))，这会给出正确的结果。

有人可以帮忙试图找到我做错的事吗？

将代码底部更改为：

if __name__ == "__main__":
    start = time.time()
    E_array, tt, kb = main()
    end = time.time()
    print('runtime: {:.3f}'.format(end-start))
    plt.figure()
    plt.title('Temperature vs time')
    plt.plot(tt*1e3,E_array/kb, linestyle = '', marker = 'o', color='black')
    plt.show()
