How can I repeat this random process 3 times so I can get 3 different versions of the variable "number"?

 function rollingdice2
i = 1;
modelaparents = 100;
modela= randi(6,1,modelaparents);
modelaparents = length(modela);
number1(1,i) = modelaparents;
while modelaparents > 0;
    i = i + 1;
    modela= randi(6,1,modelaparents);
    modelaparents = length(modela(modela ~= 6));
    number1(1,i) = modelaparents;
end

Your function with an output argument:

function number = rollingdice2
i = 1;
modelaparents = 100;
modela = randi(6,1,modelaparents);
modelaparents = length(modela);
number(1,i) = modelaparents;
while modelaparents > 0;
    i = i + 1;
    modela= randi(6,1,modelaparents);
    modelaparents = length(modela(modela ~= 6));
    number(1,i) = modelaparents;
end

calling from your main function:

numberList = cell(1, 3);
for k = 1:3
  numberList{k} = rollingdice2;
end

Now you have 3 results as elements of a cell. You've acked for 3 different results. If this detail matters, you have to compare the results with each other and call the function until you have unique results.

Thank you, I put in the code but it is giving out an empty matrix every time it is supposed to give a different "number" inside the cell. Then after that the program just crashes.

 function number = justrolling
i = 1;
modelaparents = 100;
modela = randi(6,1,modelaparents);
modelaparents = length(modela);
number(1,i) = modelaparents;
while modelaparents > 0;
    i = i + 1;
    modela= randi(6,1,modelaparents);
    modelaparents = length(modela(modela ~= 6));
    number(1,i) = modelaparents
end

 numberList = cell(1, 3)
for k = 1:3
  numberList{k} = justrolling
end
end

You have an "end" at the bottom that can only match the "function" line. That would, however, imply that your lines starting from "numerList" are part of justrolling.m . If that is the case then each time you invoked justrolling it would get down to the bottom and invoke justrolling again recusively, infinitely.

The code you have starting from "numerList" cannot be in the same function justrolling .
