I am using tikz to reproduce a Matlab picturization of a neural network. The original figure that I need to reproduce is this :
I am stuck at plotting the tanh function and the linear function inside the node.
I have tried two methods as of now : pgfplots and tikz plot function but I am unable to move the plot inside the rectangle.

You have to adjust the shift
of scope
so that its placed at the middle of node. Then just scale to required value.

what if i have to make the function of qual aspect ratio, right now it looks the height is more than the breadth.

an alternative approach:
- use of small pictures
pic
for nodes symbols - symbols are not needed to be drawn with plot function, it is sufficient to approximate it with
controls
macro - used are relative coordinates
shown are only hidden and output node

You have to adjust the shift
of scope
so that its placed at the middle of node. Then just scale to required value.
