 We perform a sweep of matrix dimensions `d` and `r`, starting with `1` and doubling each time until reaching `32768`. 
 The batch dimension is swept similarly until reaching the maximum size of `2048`. The sweeps were performed

 Since the `ORGQR` function's convention assumes only thin matrices with `d >= r > 0`, we skip the evaluation of fat 
 matrices altogether.
