# Please add Matrix<T> broadcasting.

When working with Deep NNs, there are a lot of "Z = WX + b" operations going on, where matrix WX has the same number of rows as matrix b. But, matrix b is a single column matrix, so we can't just the built in add operations. With broadcasting, matrix b will be treated like a matrix with the same number of columns as WX, but where each column is identical.
