  • 设置rng时Excel错误1004?

    当我到达“set rng=ws.Range(cell(i,7),cell(i,12)”)行(代码)时,我得到了错误1004 Application定义或对象定义的错误。在范围(单元格(i,7),单元格(i,12)之前,我没有“设置rng=ws”,而且我没有收到错误,但是它会从“窗体”而不是从“目标”复制数据。Private Sub CommandButton1_Click() Dim rng As RangeDim ws As WorksheetSet ws = Worksheets(Goals)a = Worksheets7).End(xlUp).Row For i = 2 To a If Worksheets(Goals).Cells(i, 20).Value = Red Then ws.Activate Set rng= ws.Range(Cells(i, 7), Cells(i, 12)) rng.Copy Worksheets(Scorecard).Activate b = Worksheets(Scorecard

  • OpenCV学习入门(四):RNG 伪随机问题

    在我的上一篇博客《OpenCV学习入门(三):kmeans原理及代码 》中调试kmeans时发现一个问题:每次运行时,以下两行代码int clusterCount = rng.uniform(2, MAX_CLUSTERS+ 1); int sampleCount = rng.uniform(1, 1001);生成的两个变量结果是一样的!于是我就研究了一下随机类RNG,最终找到了问题的原因。注意到程序中有如下一行代码 RNG rng(12345); 随机数产生器 OpenCV里RNG类构造函数初始化为固定的值后随机种子也是固定的,所以在相同的平台环境下,编译后每次运行它,显示的随机数是一样的rng(12345); cout

  • 如何使用Shuffling来改善rng?

    遵循Bays&Durham的伪代码实现,我试图使用c#中的内置随机数对随机数字序列进行排序。 我正在遵循的伪代码是: 生成随机数(V)的数组 生成随机数(Y) - 种子应该是数组中的最后一个数字 使用以下公式生成随机索引(y):( K * Y) m其中:K - 数组的大小Y - 生成的随机数M - 用于填充数组的随机数生成器中使用的模数 返回数组中位置Y处的元素,即V 数组中位置Y到的元素设置为Y本身,即V = Y. int); int index = (sequence.Length * randNum) ; return sequence; 我可以遵循的前几个步骤。现在,我需要返回一个shuffled数组,因此需要稍微修改伪代码。 上面代码的几点指针:cSharpRNG - > Random GenerateRandomSequence(...)的实例名称 - >使用cSharpRNG进行forloop 现在我不理解的是以下内容: 1)鉴于我正在使用内置随机,我如何获得用于填充数组的模数,因为它只是一个for循环使用cSharpRNG.Next(min,max) 2)最后一步我不完全理解它 任何帮助将非常感谢! 继塞缪尔维达解决方案后,这会有效吗?(假设我必须在一个方法中完成所有操作) public static int; sequence = cSharpRNG.Next(min, max); return sequence; randNum that should be returned instead. Made it return the array because it should return the newly shuffled array hence the for loop}
