2020年1月17日 · I am trying to prove the number of FLOPs that a matrix multiplication would use. The matrices are of the form $(n \times p)$ and $(p \times m)$.

As a means to encode linear transformation or geometric transformation; or maybe some other concepts. In the context of this answer, what I meant was to encode a set of vectors and to find dot product easily via matrix multiplication (numpy.matmul used to …

Title says it all. Is there any specific operator symbol for matrix multiplication? Not just write down side by side but symbols like cross ($\\times$).

2024年8月30日 · I've also tried this by converting the Sympy matrices to Numpy arrays and using np.matmul and np.dot, but those seem to be taking longer times. If there is a function or library to implement Bogoliubov transformations in Python, that would help too.

2020年4月8日 · The correct Python syntax would be for i in range(A.shape[0]) and would use matmul instead of dot, but you don't want the for loop anyway. You could write C=np.array([a.matmul(b) for a, b in zip(A, B)]), which is a declarative comprehension rather than an imperative for loop.

Is it possible to multiply A[m,n,k] by B[p,q,r]? Does the regular matrix product have generalized form? I would appreciate it if you could help me to find out some tutorials online or mathematical...
