Hello,
I have this piece of code:
a = zeros(12,12,12);
for i=1:12, for j=1:12, for k=1:12
a(i,j,k)=((i-5)^2+(j-6)^2+(k-7)^2)<6;
end, end, end
b = find(a);
Now I've done the same thing using gpuArray.zeros instead of zeros, and I find that the output of the find function is different. b is of size 57x1. The output of the gpuArray version (call it b1) is of size 134x1. Also, the first 57 entries in b and b1 are the same. After that, there are a bunch of zeros and some other numbers. Any idea why the find function seems to be misbehaving for gpuArray?
Thanks in advance, Ranjan
