c#中具有数组二维的方程
本文关键字：二维 方程 数组 | 更新日期: 2023-09-27 18:11:29
我有一个310行120列的数组。
我每隔10秒从串行端口获得填充这个数组的数据。
如何将此数据发送到数组的第一行，并在下一次迭代到下一行，并持续直到操作完成?
一旦完成，取数组的最大值、最小值和平均值。最后是数组中选定单元格的平均值、最大值和最小值。
这是可能的数组在c# ?
([7,31]-xxxxx.MIN([$28$5:$45$95])/(xxxxx.MAX[$28$5:$46$95]-xxxxx.MIN[$28$5:$45$95])
您在问题下面所做的注释稍微澄清了一点，但是注释的奇怪性质使这一行变得混乱:
…接收这样的字符串0#，22008,21930,00000,n/a, n/a !但只使用0#，22008,21930,00000。…
所以我现在就假设这些奇怪的字符是一个结尾。
set arraylength为120是完全没有必要的，并且二维数组不会增加可用的新方法。我们将使用锯齿数组。310的长度可能是有原因的，所以我们保留它。
因此，在每一行中，前24个"单元格"是来自流的输入。我不熟悉端口，但我可以安全地假设您可以将RS485/USB路由到流对象。单元格0、4、8、12、16和20用id填充，其中{01、02、03、04、05、06}表示它来自哪个LPC。
但是稍后在注释中你指定想要这个:
([32 6] min([28日5]:[96]))/(MAX([28日5]:[96])分钟([28日5]:[96]))
即使在Excel中，这也会对这些id取最小/最大/平均值。在这段代码中我们要避免这种情况，它会忽略这些列。

应该是不言自明的。创建一个LaserArray，初始化流，读取数据，然后享受结果。
还有，我很无聊，又在度假，所以我才这么详细地回答一个一年前的问题。
也声誉。
