我有两个向量.我想制作第一个矢量的条形图(简单,正确).扭曲是第二个向量的每个元素都是第一个向量的每个元素的标准偏差(它本身是4个其他值的平均值).我怎样才能做到这一点？

有问题的载体:

-4.6521175 0.145839723
 1.1744100 0.342278694
-0.2581400 0.003776341
-0.3452675 0.073241199
-2.3823650 0.095008502
 0.5625125 0.021627196

即,如何将第二列向量的元素作为误差条添加到第一列向量中的相应元素？

注意:在你问之前,是的,我在这个网站上进行了大量搜索,并进行了大量的谷歌搜索,但我的问题更具体,即我发现的与我需要的不符.

有人可以帮助我 - 我需要一个正则表达式,只匹配包含字符ADFHKMPRTWCEGILNQSVY和NOTHING其他的行.

我需要遍历看起来像这样的文本行:

假设我有一些变量,$x, $y, $z, $a, $b, $c并且我想确保它们都具有相同的值.

我可以测试类似的东西,if ($x == $y == $z == $a == $b == $c)以避免多个二进制比较,即(if $x == $y and $x == $z and $y == $z ...)？

有什么方法可以做一切简短的测试比较吗？
