function states = markov_1(time, transmat)
format long
transmat = [0.9972  0.00022831; 0.5  0.5];
n = length(transmat);
states = zeros(1, n);
states(1)=1;
for i = 1:time
    states = states * transmat;
end

[for end] loop is working perfectly ok, but there is an error in your defined function's input arguments. See the corrections:

time =3;
transmat = [0.9972  0.00022831; 0.5  0.5];
markov_1(time, transmat)
function states = markov_1(time, transmat)
format long
%transmat = [0.9972  0.00022831; 0.5  0.5];
n = length(transmat);
states = zeros(1, n);
states(1)=1;
for i = 1:time
    states = states * transmat;
end
end

The code @Sulaymon Eshkabilov posted will already work for user-provided time, if you write the code to markov_1.m

function states = markov_1(time, transmat)
    n = length(transmat);
    states = zeros(1, n);
    states(1)=1;
    for i = 1:time
        states = states * transmat;
    end
end
