The Challenge is to create the unique array for a long and wide array.
Difficulties are that the normal unique(a,'rows') function call will suffer a Memory crash on Cody. c=randi(4,9000000,48,'uint8')-1;
The second part of the challenge is Execution Speed.
The data is small integer representing data permutations of items like DNA and Rubik's cube faces.
Input: Array of uint8 of dimensions (m, 48) with values 0:3
Output: Array Equivalent to unique(A,'rows')
1) Columns can be merged to form a reduced number of columns 2) Unique has the option to provide an Array and a sorting Index
