Hey!!!plz help...i am unable to pass each vector from matrix to function using a for loop....plz tell where lies the fault

clc
base= {1000 1000 551 1449}
slope= {0 0 2 -2}
season= {0 200 200 200}
noise= {100 100 100 100}
choice= input('enter your choice')
switch choice
    case 1
        disp ('simple moving average')
        for i=1:1:4
        simpmovaverage(base(i),slope(i),season(i),noise(i));
        end
    case 2
        disp('finish')
end
