Dot product of two vectors in tensorflow

Question

I was wondering if there is an easy way to calculate the dot product of two vectors (i.e. 1-d tensors) and return a scalar value in tensorflow.

Given two vectors X=(

Answer 1

or

tf.matmul(tf.transpose(x),y)

depending on the dimensions of x and y
