我想找出Foo f = 1函数,但系统给出了警告:

  

round(mf)中的错误:数学函数的非数字参数

代码如下所示:

    [TestMethod]
    public void LocationNameSearch()
    {


// Create new stopwatch.
Stopwatch stopwatch = new Stopwatch();

// Begin timing.
stopwatch.Start();

// Import the search method.


    System.Threading.Thread.Sleep(2000);



// Stop timing.
stopwatch.Stop();

//Assert
Assert.IsTrue(stopwatch.ElapsedMilliseconds < 3000, **2000**);


}

答案 0 :(得分:1)

这是一篇过时的文章,但是我要为以后的案例做答复(我也遇到了同样的问题)

应该像定义不带引号的公式一样简单:

f=cbind(I_like_to_drink,I_drink_hard_liquor,I_have_drank_in_the_morning,I_have_drank_in_the_work,I_drink_to_get_drunk,I_like_the_taste_of_the_alcohol,I_drink_help_me_sleep,Drinking_interferes_with_my_relationships,I_frequently_visit_bars)~1
