Why doesn't exist F.mul function(element-wise multiplication)?

[machanic]

I mean, F.mul is element-wise multiplication.
My network produce two scores, I want to multiply the two scores to produce final score
score = F.mul(s1, s2) I did not find F.mul or F.multiply
So, I am writing the following code:
score = s1 * s2

Can this work and back propagation?

[kmaehashi]

score = s1 * s2

Yes, this operation supports backprop. __mul__ operator is defined for Variables. https://github.com/chainer/chainer/blob/v4.0.0b4/chainer/functions/math/basic_math.py#L865
