matlab 程序 求助

下面是一教材例题 我按照教材输入 却 不能运行 老是报错。哪位高手帮忙一下。谢谢了。
M文件为
Function [varargout]=xxfx1(x,y)
%方差分析表
alpha1=0.05
alpha2=0.01
x=x(:)
y=y(:)
n=length(y)
SST=sum((y.*y))-(sum(y)).*(sum(y))/n
lxx=sum(x.*x)-sum(x).*sum(x)/n
lxy=sum(x.*y)-sum(x).*sum(y)/n
SSR=lxy.*lxy/lxx
SSE=SST-SSR
df1=1
df2=n-2
df3=n-1
VR=SSR/df1
VE=SSE/df2
Fb=VR/VE
F=finv(1-[alpha1;alpha2],df1,df2)
F1=min(F)
F2=max(F)
if Fb>F2
tst='**'
else if (Fb>F1)&(Fb<=F2)
tst='*'
else
tst=' '
end

format short g
table=cell(4,7)
table{1,1}='方差来源’
table{2,1}='回归’
table{3,1}='剩余’
table{4,1}='总和’
table{1,2}='偏平方和’
table{2,2}=SSR
table{3,2}=SSE
table{4,2}=SST
table{1,3}='自由度’
table{2,3}=df1
table{3,3}=df2
table{4,3}=df3

小错误不少，调通了。
