Tensorflow tensor operation function set

Sort it out for my own use TensorFlow Some operations commonly used in ：

1.  Multidimensional tensor calculation

How to calculate the multiplication of two three-dimensional matrices ？tensorflow Take the previous dimension as batch, Perform ordinary matrix multiplication on the last two dimensions . in other words , The dimension before the last two dimensions , All need to be the same

for instance ：a = [2, 3, 2] ,   b = [2, 2, 3] It's understandable a Two of the matrix 3*2 The matrix of corresponds to multiply by b Two of the matrix 2*3 Matrix
