使用 LINQ 计算浮点数组的平均值

Question

Beginner here,

I have a list that stores arrays of floats (each array reflects a vector, if it matters):

List<float[]>

My goal is to calculate the average values of all these arrays (that is, the vector that contains the average of each element), and store it in an another array of floats.

It's my understanding that using LINQ for my use case would be a good practice. I've given it a try, followed the relevant documentation, and I'm having some trouble.

I would really appreciate seeing what such LINQ query should look like.

Answer 1

You can do it with a help of Linq:

List<float[]> source = ...

var result = source
  .Select(array => array.Average()) // average of each element (array)
  .ToArray();                       // materialize as an array of floats
