Hello, how can I give 90% probability to elements of a vector that do not repeat themselves, and to elements that repeat 10%.

for example:

I have a vector

vector = [10 15 15 23 20 40]

give a probability of 90% to the numbers 10,23,20,40, and a probability of 10% to the numbers that are repeated, that is, 15,15.

and store it in a variable

thanks in advance

Have you already found a way to separate those two groups of numbers? That seems the first step to me. Then you can sample them in a 1:9 ratio.

separate them in what way?

vector = [10 23 20 40 15 15]

like that?

在 MATLAB Online 中打开

Did you try a simple for loop?

vector = [10 15 15 23 20 40];
probabilities = zeros(1, length(vector));
for k = 1 : length(vector)
    if sum(vector == vector(k)) >= 2
        % Repeated
        probabilities(k) = 0.1;
    else
        % Not repeated
        probabilities(k) = 0.9;
    end
end
probabilities % Show in command window.
probabilities = 1×6
    0.9000    0.1000    0.1000    0.9000    0.9000    0.9000

Hello my friend how are you? I hope it's ok.

could you help me with this question? https://la.mathworks.com/matlabcentral/answers/1652655-how-can-i-choose-non-repeating-values-with-a-probability-of-90-and-10

is very similar to this question

Thanks in advance
