element-wise product numpy
Numpy arrays use element-wise multiplication by default. Check out numpy.einsum, and numpy.tensordot. I think what you're looking for is ...,For elementwise multiplication of matrix objects, you can use numpy.multiply : import numpy as np a = np.array([[1,2],[3,4]]) b = np.array([[5,6],[7,8]]) np.multiply(a ... ,If both a and b are 1-D arrays, it is inner product of vectors (without complex ... If a is an N-D array and b is a 1-D array, it is a sum product over the last axis of a ... ,The product of x1 and x2, element-wise. Returns a scalar if both x1 and x2 are ... ,The product of x1 and x2, element-wise. Returns a scalar if both x1 and x2 are scalars. Equivalent to x1 * x2 in terms of array broadcasting. >>> x1 = np.arange(9.0).reshape((3, 3)) >>> x2 = np.arange(3.0) >>> np.multiply(x1, x2,numpy. multiply (x1, x2, /, out=None, *, where=True, casting='same_kind', ... ,The product of x1 and x2, element-wise. This is a scalar if both x1 and x2 are scalars. Equivalent to x1 * x2 in terms of array broadcasting. >>> x1 = np.arange(9.0).reshape((3, 3)) >>> x2 = np.arange(3.0) >>> np.multiply(x1, x2, numpy.multiply¶. numpy.multiply(x1, x2[, out]) = <ufunc ..., Are you sure a and b aren't NumPy's matrix type?
