Difference between this expmv and the built-in expmv? #2
Description
As of R2023b, there also exists a built-in expmv in MatLab. Is there any difference between the two? (For instance, according to its documentation, the built-in one does not support the half-precision data type. Are there any other differences?)
Besides, I notice that in some other languages, it is possible to directly calculate not only the product of a matrix exponential and a vector, but also the product of a matrix power and a vector (e.g., this example); regretfully, I cannot find a mpowerv function in MatLab (There are expm, expmv, and mpower (as well as sqrtm), but not mpowerv.). Does there exist a function mpowerv analogous to your expmv?
