divide boolean array

[robin123_hood]

hi sir, i just want to ask on how to divide  a 1-d boolean array. for example i want to put the first 32 bits into column 1, then the 2nd to column to and so on.. i just want to have a 2-d array of 32 bits per cell.. thank you 🙂

Try "reshape array" (nothing to do with division). 🙂

My first thought was Reshape Array, but it doesn't do what I'd expect if the length of the input array wasn't a multiple of 32.  It makes each column 32 elements long, but divides the input array among them.  I don't know which behavior is desired and I expect that my top implementation isn't optimum.

Swap the two size inputs to the reshape function, then transpose afterwards.

Here is the simplest reshape code that pads the last row if needed.

 

If you can guarantee that the size is divisible by 32, or if you want to discard incomplete rows, just wire the "IQ" output directly to the upper size input and discard the extra math.

If you later want to process 32 elements at a time, reshaping into rows of 32 is much more convenient, e.g. by using autoindexing in a FOR loop, processing one row at a time. Of course if you want columns instead, transpose after reshaping as already mentioned.

thanks sir 🙂
