Once you know that it's linear, you know that there's some way to describe this function as matrix multiplication.

一旦你知道它是线性的 你就知道有一些方法可用法来描述数。

So that is the entire operation, two matrix products each with a bias added, and a simple clipping function in between.

所整操作就是两积各自加上一偏置项，并且中间有一简单的裁剪数。

You could even define this as matrix vector multiplication when you put the matrix on the left of the vector, like its a function.

你甚至可把它定义为向量法当你把放在向量的左边 就像它是一数。

Specifically, since it's a function that goes from three dimensions to one dimension, there will be a one by three matrix that encodes this transformation.

具体来说 因为它是一从三维到一维的数 会有一1×3的来编码变换。
