图像转为数组然后求和

[luopeng2019]

该数组为640*512的图像，想要将该数组求和，请问怎么求？

The array is a 640*512 image. I want to sum the array. How do I find it?

Just use "add array elements". What is the datatype of the array? It it is integer with few bytes, Make sure to convert to so something (e.g. I32) that can hold the result first.

(We can typically help better looking at a VI instead of pictures.)
