Hello everybody,
is there a function in Matlab which generates an array containing all ordered samples of length k taken from a set of n elements , that is all the k-tuples where each can be any of the , and whose total number is ?
Or can anybody suggest a simple code to generate all of them? I am guessing it involves the iterative use of datasample function checking that every new generated sample is different from the previous ones, but I couldn't find so far a satisfactory way to write it

For and ,
n = 20;
k = 5;
result = dec2base(0:n^k-1, n); %generate all n^k samples with replacement, as char vector 0-9 + A-Z
result = result - '0' + 1; %convert character to numbers 1-10, A-Z get converted to 18+
result(result>17) = result(result>17) - 7 %convert 18+ to 11+
For greater n you'll have to use Jan's answer.
