百度,GOOGLE还有MATLAB的帮助里都只有一点点资料。
我想知道多点关于这个函数的知识啊。。
fsurfht(fun,xlims,ylims,p1,p2,p3,p4,p5) 这边p1p2表示什么呢?
还有这段:
Create a function containing the following commands, and name it gauslike.m.
function z = gauslike(mu,sigma,p1)
n = length(p1);
z = ones(size(mu));
for i = 1:n
z = z .* (normpdf(p1(i),mu,sigma));
end
The gauslike function calls normpdf, treating the data sample as fixed and the parameters µ and σ as variables. Assume that the gas prices are normally distributed, and plot the likelihood surface of the sample.
这边事说画了个正态分布??
我对这个函数一点都不懂哎,搜也搜不出什么,只好来这边问问。
请各位帮助我一下。我想知道用法和具体的一些例子。这是老师的课后作业,感激不尽啊
