comment The phrase “coordinate-wise” and its meaning
So, another potential interpretation of that, it sounds like, is you can apply a function $f: \Re^1 \mapsto \Re^1$ coordinate-wise to a matrix or array by applying it element-wise.

comment The phrase “coordinate-wise” and its meaning
Ah. I see your point. So, if for example I have a scalar function $\sigma$ I want to apply to the elements of a vector/matrix (eg, $\mathbf{Y} = \mathbf{\sigma}(\mathbf{X})$ ), I could say $\mathbf{\sigma}$ is evaluated "coordinate-wise" on elements of $\mathbf{x}$. You should write up your response as an answer so I can accept it.
