Use arrayfire function

[huibinchang]

Hi, Filipe. I want to know how to use the arrayfire function as arrayfire.matmul for matrix multiplication and other functions in arrayfire.linalg. Does it exist a easy way for this?
I tried to use af.arrayfire.matmul. However, it failed since it can not recognize the data type. To run the code, I have to copy the data from GPU to CPU, and then use numpy function instead of afnumpy.

Thanks.

Hi,

This is kinda of a hack but you can do it like this:

a = afnumpy.ones((3,3))
b = afnumpy.array(afnumpy.arrayfire.matmul(a.d_array, a.d_array))

Thanks for your quick response. I will have a try!

By the way, afnumpy is really efficient for me (Only use Matlab before).

Thanks!

BTW in the latest afnumpy afnumpy.dot does matrix multiplication when given 2D arrays as input, just like regular numpy.

Sounds great! I will have a try! Huibin //////////////////////////////////// 常慧宾 数学科学学院 天津师范大学 CHANG Huibin, School of Mathematical Sciences, Tianjin Normal University, P.R. China 2018-06-01 12:46 GMT-07:00 Filipe Maia <notifications@github.com>:
