I have a question about how to create the following array in a simple, concise way (for any permutations).
Think of a 4 digit lock, but numbers allowed are not 0-9, but 1-6 or 0-17 (or any other range).
For 0-9 there are 10^4 permutations, which should be a 10000 x 4 array, each row showing one of the permutations.
I thought of building the array from 4 vectors (thousand, hundred, tens, ones), but that is also cumbersome when looking at a 7digit lock with 11 possible numbers for each digit.
4 digits, possible numbers for each digit 1 - 6 (1296 permutations)
unity_ones = [1;6];
which means that the ones vector can be created by:
n = 1296/6;
ones_vector = ;
ones_vector = [ones_vector,ones];
Then one can do the same for the tens_vector, hundreds_vector and thousands_vector... This seems not very efficient. I am sure there is an easier, one or two liner out there.... :-)
