Multiply two lists element wise python
Webnumpy.dot. #. numpy.dot(a, b, out=None) #. Dot product of two arrays. Specifically, If both a and b are 1-D arrays, it is inner product of vectors (without complex conjugation). If both a and b are 2-D arrays, it is matrix multiplication, but using matmul or a @ b is preferred. If either a or b is 0-D (scalar), it is equivalent to multiply and ... WebI have two lists, e.g. a = {1,2,3} b = {4,5,6} I'd like to multiply each element from the first list with each element from the second, like this: {1*4, 2*4, 3*4, 1*5, 2*5, 3*5, 1*6, 2*6, 3*6} I only need the result: {4, 5, 6, 8, 10, 12, 15, 18} I have found a solution for this:

WebFor example, whereas 1/a returns the element-wise inverse of each float in the array, 1/q1 returns the quaternionic inverse of each quaternion. Similarly, if you multiply two quaternionic arrays, their product will be computed with the usual quaternion multiplication, rather than element-wise multiplication of floats as numpy usually performs.
