👉 Gemmery is a method of matrix multiplication in linear algebra, used to perform matrix-vector products. It involves multiplying two matrices together and then taking their dot product with each other's vectors. This operation is often denoted as "gemm" or "gem". For example: ```python import numpy as np A = np.array([[1, 2], [3, 4]]) B = np.array([[5, 6], [7, 8]]) C = A
