Hello everybody, I have a problem with this following issue:
I want to select X=1 or 2 randomly but if in this code if X=2
happens 3 times consecutively ,for the next time, program should select X=1 and vice versa.
(I mean 1 or 2 should be selected randomly but with a threshold==3 after that it should choice another value)
my code is here:
Please if you know it tell me about that, I really stuck (Thanks in advance)
Z{1,1}={0};
for h=1: 45
Y = {'L', 'R'};
%% Here is my problem (Setting a threshold)
X = randi([1, 2], 1); % Get a 1 or 2 randomly.but I want to set a threshold that if X=2 happens 3 times consecutively for the next time choice another value and vice versa. (I mean (for example) it should not select X=2, 4 times consecutively in this loop randomly )
Z{1,h} = Y(X);
end

Make X an array, and if X(h), X(h-1) and X(h-2) are all the same, get a new X. Like this:
numTrials = 45;
maxRunLength = 3;
Z{1}={0};
Y = {'L', 'R'};
for h = 1 : numTrials
% Here is my problem (Setting a threshold)
X(h) = randi([1, 2], 1); % Get a 1 or 2 randomly.but I want to set a threshold that if X=2 happens 3 times consecutively for the next time choice another value and vice versa. (I mean (for example) it should not select X=2, 4 times consecutively in this loop randomly )
if h >= maxRunLength
theRange = range(X(h-maxRunLength+1 : h))
if theRange == 0
% They're all the same. Swap the current X so 1 is now 2 or 2 is now 1
X(h) = 3 - X(h);
end
end
Z(h) = Y(X(h)); % Use parentheses, not braces.
end
% Show values in command window
X
Z
You'll see
X =
Columns 1 through 22
1 2 1 1 2 1 2 1 2 1 2 1 1 2 2 1 2 2 1 1 2 1
Columns 23 through 44
1 2 1 1 2 1 1 2 2 1 1 2 1 2 1 1 2 2 1 2 1 1
Column 45
2
Z =
1×45 cell array
Columns 1 through 15
{'L'} {'R'} {'L'} {'L'} {'R'} {'L'} {'R'} {'L'} {'R'} {'L'} {'R'} {'L'} {'L'} {'R'} {'R'}
Columns 16 through 30
{'L'} {'R'} {'R'} {'L'} {'L'} {'R'} {'L'} {'L'} {'R'} {'L'} {'L'} {'R'} {'L'} {'L'} {'R'}
Columns 31 through 45
{'R'} {'L'} {'L'} {'R'} {'L'} {'R'} {'L'} {'L'} {'R'} {'R'} {'L'} {'R'} {'L'} {'L'} {'R'}
