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

所以整操作就是两矩阵乘积各自加偏置项，并且中间有简单的裁函数。

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

旦你它是线性的 你就有些方法可以用矩阵乘法来描述这函数。

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

你甚至可以把它定义为矩阵向量乘法当你把矩阵放在向量的左边 就像它是函数。

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 因为它是从三维到维的函数 会有1×3的矩阵来编码这变换。
