Hello i need to simulate specific number of games of lottery 6 out of 45 and compare if i get 1s 2s...6s and compare my winrate. I am not allowed to use functions designed specifically for matlab though.
How would i count my similarities between "tipps" and "lottozahl"? counts doesnt seem to work
clc
lottospiele = input ('´Wie oft wollen Sie Lotto spielen?');
while lottospiele > 0
if lottospiele > 0
tipps = randperm (45,6);
lottozahl = randperm(45,6);
disp (lottozahl)
disp(tipps)
counts=histc(tipps, 46:6)
lottospiele = lottospiele - 1;
end
end

I would suggest a loop. Once you have generated the winning number and your choice you need to loop through either of them to count the number of elements that are shared.

This might be instructive. Adapt as needed:
official = [1,3,32,19,4,21]
myPick = [2,4,19,25,32,40]
% Find the mismatches which are in the official but not in myPick
mismatches = setdiff(official, myPick)
% Find the mismatches which are in myPick but not in the official
mismatches = setdiff(myPick, official)
% Find out which numbers are in both myPick and in the official
[ia, ib] = ismember(myPick, official)
myMatches = myPick(ia)
You'll see:
official =
1 3 32 19 4 21
myPick =
2 4 19 25 32 40
mismatches =
1 3 21
mismatches =
2 25 40
ia =
1×6 logical array
0 1 1 0 1 0
ib =
0 5 4 0 3 0
myMatches =
4 19 32
