Hey @Lukas Lehrman, hey there is a minor mistake in your code as 'A' is 2x2 matrix and 'v' is 2x1 matrix and the resultant matrix obtained after their multiplication is 2x1 matrix, thereby you should assign the value to answer by doing answer(i,:).
pvalues = [0:0.01:1];
v = [1;0];
for i=1:length(pvalues)
p=pvalues(i)
A = [2-p 0.25*p;p (1.25-(0.25*p))];
answer(i,:) = (A^25)*v;
end
max(answer)
hope it resolved your issue.
