![]() If you want the fusing version of this operation in 0.5, you need z. = tmp # write the tmp into z, equivalent to copy!(z, tmp) * y # allocate a new temporary array for elementwise x * y In particular, it does not fuse with the assignment in. * operator is defined, but it is just a function call and is not fusing. I would also strongly recommend the BenchmarkTools package, and using myfunc(.) rather than myfunc(.), since will run a timing loop for you and gather statistics. (although possibly not the fastest) would be in a for loop and allocating each vector at a time. Here are a few old threads that I have referred in the past in this regard:ĭon’t do timing measurements in global scope. you could do the following and Matlab would do amazing and magical things for you. *(x, y)? Instead, I can feel free to use regular equal sign = and auto fusing dot x.*y? Am I right? Any comments are appreciated!! I ran the following code: foo!(x, y, z) = z. This definition says that C (i,j) is the inner product of the i th row of A with the j th column of B. If A is an m-by-p and B is a p-by-n matrix, then C is an m-by-n matrix defined by C ( i, j) k 1 p A ( i, k) B ( k, j). I’m using v5.0 and wondering what the current status is for element-wise vector multiplication (except the newly merged PR, which will only affect the future versions). Syntax C AB C mtimes (A,B) Description example C AB is the matrix product of A and B. Hi, Sorry for asking once again this frequently-asked question.
