I am looking into this numba example:
https://numba.pydata.org/numba-doc/dev/cuda/examples.html
There is a section where part of an array is loaded into another:
sA[tx, ty] = A[x, ty + i * TPB]
I see that sA is a 2d array of size 16x16. I know I can access 2d array positions with sA[i][j], but this syntax using a comma inside the [] I don really understand.
What is that doing?
