How can i save the outputs of a function inside that function so i can recall that function in another script and plot with it output ???

function [x] = compute(W, k1, k2, d)

x1 = W / k1; x2 = ( W + 2 * k2 * d ) ./ ( k1 + 2 * k2 ); k1 = 10000; k2 = 15000; d = 0.1;

if x1 < d;

    x = x1;

else x = x2;

end

this is my first function, after i set the value W i get an output, now i want to save that output inside this function so i can use it in my next script which is this one:

W = 0:50:3000;

k1 = input ('Please enter a value for k1=', 's');

k1 = str2num(k1);

a = isempty(k1);

while a == 1;

    k1 = input('Wrong Input!!! Please enter a value for k1=' , 's');
    k1 = str2num(k1);
    a = isempty(k1);

end

while a == 0;

    k2 = input('Please enter a value for k2=','s');
    k2 = str2num(k2);
    b = isempty(k2);

    while b == 1;

        k2 = input('Wrong Input!!! Please enter a value for k2=','s');
        k2 = str2num(k2);
        b = isempty(k2);

    end

        while b == 0;

            d = input('Please enter a value for d=','s');
            d = str2num(d);
            c = isempty(d);

            while c == 1;

                d = input('Wrong Input!!! Please enter a value for d=','s');
                d = str2num(d);
                c = isempty(d);
            end

            if c == 0; 
            end

          break;
        end

        break;

end

x = compute(W, k1, k2, d);

plot(W, x);

xlabel('Distance(m)');

ylabel('Weight(N)');
