Check gpuArray double or single?
显示 更早的评论
I'm pretty sure a gpuArray has a type (e.g., single or double). But i'm not sure how to check it. The function isa does not work for gpuArray.
A = gpuArray(single(1));
B = gpuArray(double(1));
isa(B,'double')
isa(B,'single')
You get both 0s.

The isa function works fine, but it answers a different question than you want to be answered. Instead, ask your question using the classUnderlying function.

isaUnderlying is the direct analogue.

Right, classUnderlying came to my mind first and I forgot to check for a function that is to isa like classUnderlying is to class. Use isaUnderlying as Joss suggested.
