If we take a closer look in the scalar multiplication process, we can see that we can calculate the whole vector at once: In the scalar code, Vec.x is multiplied with the first four elements of the matrix. Those

In this program, user is asked to enter the size of two matrix at first. The column of first matrix should be equal to row of second matrix for multiplication. If this condition is not satisfied then, the size of matrix is again asked using while loop. Then, user is asked to enter ...

>>It's funny how in college they tell you that the programmer need not worry with the low level issues of hardware implementation, yet even a simple problem such as matrix multiplication can cause such problems.This is the difference between theory and practice. QED (Quite Easily Doh...
In PyTorch, do matrix multiplication functions such as torch.matmul and torch.nn.functional.linear internally call cublasGEMM? If so, where can I find these calls, or is there any documentation that explains these calls? Activity malfet commented on Jan 16, 2025 malfet on Jan 16, 2025 Cont...
To answer your question about how small they are, we can assume I can convert them to any size that we can have a fast sparse matrix-multiplication for. b) It is actually not a chain matrix-product, and not based on a tree. I know it would help to have...
