When I was compiling my simple matrix multiplication app, i noticed that riscv vector compiler, optimizes the loop out of the execution and does not use vector extension instructions at all. Is there any hint on which flags to use to optimize enough to use vector extension, but not to rem...
We say matrix multiplication is "not commutative". Sometimes it does work, for example AI = IA = A, where I is the Identity matrix, and we'll see some more cases below. Inverse of a 2×2 matrix In general, the inverse of the 2×2 matrix X = a b c d is given by: X−1...

1(c)), but after being passed through the non-linear ruler (Fig. 1(b)) it results in the observed bimodal distribution (Fig. 1(a)). The discovery of a non-linear ruler should prompt a revision of the initial inference about the presence of two discrete sub-populations. Our main ...

I am very inexperienced with Matlab (moving to Matlab from Excel because I'm starting to have complicated matrix problems to solve). I have a 17 x 17 matrix that I want to do a division operation on in which I divide each element in the matrix by every ...
The first line in the loop, computing \(q = Gp\), is the most expensive one, but it is relatively cheap, the multiplication of a matrix and a vector. Of course an iterative algorithm is only useful if it converges quickly enough. In our experience this is the case for conjugate ...
