Running 2 found variables thru another script

So this is based off a question I had earlier involving this code below.

function fit=get_linear_fit_2(data)

s=size(data);

Syx=0;

Sxx=0;

Sy=0;

Sx=0;

for n=1:s(1)

Syx=data(n,1)*data(n,2)+Syx;

Sxx=(data(n,1))^2+Sxx;

Sx=data(n,1)+Sx;

Sy=data(n,2)+Sy;

end

m=[Sxx,Sx;Sx,s(1)];

c=[Syx;Sy];

disp(m)

disp(c)

fit=Cramers_rule(m,c)

end

%%%%%%

So at the end I get an "m" and a "c", so I have a cramers rule script that I want to run these thru and get an answer for using the command I have above, can anybody give any insight as to how I can modify that line to work. I get the "too many output arguments" error when I run it thru.

Cramers rule code

function Cramers_rule(m,c)

s=size(m);

n=1;

dm=det(m);

while s(2)>=n

a=m;

a(:,n)=c(:);

y(n)=det(a)/dm;

disp(y(n))

n=n+1;

end
