Dear list, I have a 4D array, A, that has the shape (NX, NY, 2, 2). I wish to perform matrix multiplication of the 'NY' 2x2 matrices, resulting in the matrix B. B would have shape (NX, 2, 2). I believe that np.einsum would be up to the task, but I'm not quite sure of the subscripts I would need to achieve this.
Can anyone help, please? cheers, Andrew. -- _____________________________________ Dr. Andrew Nelson _____________________________________
