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 你知道有一些方法可用矩阵乘法来描述这个函。

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

所整个是两个矩阵乘积各自加上一个偏置项，并且中间有一个简单的裁剪函。

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矩阵向量乘法当你把矩阵放在向量的左边 像它是一个函。

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 因为它是一个从三维到一维的函 会有一个1×3的矩阵来编码这个变换。
