统计计算作业：
自己根据qqplot方法设计一个myqqplot
function h = myqqplot(x)
y = sort(x);
[m,n]=size(y);
pp=((1:n)'-0.5)./n;
x = norminv(pp);
hh = plot(x,y,'-p');
x=x';
r=corrcoef(y,x);
b=r(1,2);
text(0.8*(min(x)+max(x)),0.8*(min(y)+max(y)),['r=' num2str(b)]);
xlabel('Standard NormalQuantiles')
ylabel('Quantiles of InputSample')
title ('QQ Plot of Sample Dataversus Standard Normal')
