Oct 14 2016 nbsp 0183 32 For ndarrays is elementwise multiplication Hadamard product while for numpy matrix objects it is wrapper for np dot source code As the accepted answer mentions np multiply always returns an elementwise multiplication Notably it preserves the type of the object if a matrix object is passed the returned object will be matrix if This is something that in theory a good compiler should do by itself, however I made a try with my system (g++ 4.6.3) and got about twice the speed on a 300x50 matrix by hand unrolling 4 multiplications (about 18us per matrix instead of 34us per matrix):
Feb 3 2016 nbsp 0183 32 I have a list my list 1 2 3 4 5 How can I multiply each element in my list by 5 The output should be 5 10 15 20 25 I want to perform an element wise multiplication, to multiply two lists together by value in Python, like we can do it in Matlab. This is how I would do it in Matlab. a = [1,2,3,4] b = [2,3,4,5] a .* b = [2, 6, 12, 20] A list comprehension would give 16 list entries, for every combination x * y of x from a and y from b. Unsure of how to map this.

While this code may solve the question, including an explanation of how and why this solves the problem would really help to improve the quality of your post, and probably result in more up-votes.
The width used for the multiplication will be the widest of a b and c In your case b is the widest at 64 bits so 64 bit arithmetic will be used for the multiplication You are then assigning the result to a 32 bit wide wire c So the 64 bit result will be truncated to 32 bits the MSBs will be lost which may lead to a strange result eg Dec 15, 2009 · Since multiplication is more expensive than addition, you want to let the machine paralleliz it as much as possible, so saving your stalls for the addition means you spend less time waiting in the addition loop than you would in the multiplication loop. This is just my logic. Others with more knowledge in the area may disagree.
