Detailed Description

Layer that represents a Matrix Multiplication.

Let A be op(getInput(0)) and B be op(getInput(1)) where op(x) denotes the corresponding MatrixOperation.

When A and B are matrices or vectors, computes the inner product A * B:

matrix * matrix -> matrix
matrix * vector -> vector
vector * matrix -> vector
vector * vector -> scalar

Inputs of higher rank are treated as collections of matrices or vectors. The output will be a corresponding collection of matrices, vectors, or scalars.

For a dimension that is not one of the matrix or vector dimensions: If the dimension is 1 for one of the tensors but not the other tensor, the former tensor is broadcast along that dimension to match the dimension of the latter tensor. The number of these extra dimensions for A and B must match.

Warning
Do not inherit from this class, as doing so will break forward-compatibility of the API and ABI.
