a=fun(1,2) is used to call function fun and at the same time we use fun=randi(3,3) a=fun(1,2) to extract 1st row 2nd column of fun

function out = yourfun(a,b)
m = randi(3,3);
out = m(a,b);
end
or
function out = yourfun2(a,b)
global m;
out = m(a,b);
end
% example use function yourfun2
>> global m
>> m = randi(3,3);
>> out = yourfun2(1,2);
