dot falls back to LinearAlgebra/src/generic.jl

[rveltz]

Hi,

I have another difficulty. It seems dot falls back to LinearAlgebra/src/generic.jl in both 0.7 and 0.6.4

Can it be fixed by?

import Base.LinAlg: dot, norm dot(a::ArrayFire.AFArray,b::ArrayFire.AFArray) = ArrayFire.dot(a,b,UInt32(0),UInt32(0))[1]

Also I had to extract the first element, it would be better for ArrayFire.dot to return a scalar.

Thank you

Best regards

This dot function is giving me the error:

which seems like a bug in error handling
