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

所整个操作就是两个矩各自加上一个偏置项，并且中间有一个简单的裁函数。

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用矩法来描述这个函数。

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

你甚至把它定义为矩向量法当你把矩放在向量的左边 就像它是一个函数。

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 因为它是一个从三维到一维的函数 会有一个1×3的矩来编码这个变换。
