In LabVIEW you can use the Add Array Elements function from the Numeric Palette to calculate the sum of a 1D array. Use this function in a For Loop and connect the input array and also the output array with Auto-Indexed Tunnels. If you need to calculate the sum of the rows you need ...

Given a 2D immutable array, Write an efficient program to support any given sub-rectangle sum query in this 2D matrix. A simple solution is to add each entry inside the sub-rectangle. The runtime is O(n * m). The problem of this solution is that for a given 2D matrix, we always s...
如果其中有一个或多个值是浮点数，则返回浮点数。PHP 4.2.1 之前的版本修改了传入的数组本身，将其中的字符串值转换成数值（大多数情况下都转换成了零，根据具体制而定）。语法array_sum(array)参数描述array必需。规定输入的数组。例子<?php $a=array(0=>"5",1=>"15",2=>"25"); echo array_sum($...

There is also an old mathematical function that performs precisely the calculation you specified. MMULT is a very fast function but, despite that, I would more often use the other formula =MMULT(rowArr,colArr#)=SUM(TOCOL(rowArr)*colArr#)...
