One of the most common questions we see on the ArrayFire Google Group pertains to methods to manipulate the dimensions of ArrayFire array objects. Thus we will continue the “Learning ArrayFire from scratch” blog series by providing a detailed discussion of the numerous functions that permit you to change the dimentionality, flatten, flip, join, shift, transpose, and tile arrays.
