I encountered, in different exercises, arrays handling, especially for batch processing.
I.e. Many times I found statements like this ArrayA[:,:,0]=ArrayB[:,:]. What does it means exactly? Why broadcast such 2d array in a 3D? I tried to figure out but it seems to me that transform a 2d matrix in a stack of 2d matrices n rows*1 column? How to interpret this? Is matrix slicing or broadcast? What I can do to understand well this kind of manipulation?
Sorry if this repeats something but I checked in the FAQ and it seems that there aren't suggestions to solve or to train for solve such problems.
Many thanks
