numpy.matmul()
numpy.matmul
-
numpy.matmul(a, b, out=None) -
Matrix product of two arrays.
The behavior depends on the arguments in the following way.
- If both arguments are 2-D they are multiplied like conventional matrices.
- If either argument is N-D, N > 2, it is treated as a stack of matrices residing in the last two indexes and broadcast accordingly.
- If the first argument is 1-D, it is promoted to a matrix by prepending a 1 to its dimensions. After matrix multiplication the prepended 1 is removed.
- If the second argument is 1-D, it is promoted to a matrix by appending a 1 to its dimensions. After matrix multiplication the appended 1 is removed.
Multiplication by a scalar is not allowed, use
*instead. Note that multiplying a stack of matrices with a vector will result in a stack of vectors, but matmul will not reco
