UC知道matlab中的 isomap算法
来源：百度知道 编辑：UC知道 时间：2024/07/02 15:05:05
现在程序都编好了，就是有点小问题：
alpha = 0.5;
K = 10;
load data.mat
D=distance(data, labels, alpha);
options.dims = [2];
[Y, R, E] = IsomapII(D, 'k', K, options);
运行后会出现如下问题：
1：
??? At compilation "data" was determined to be variable. As a variable,
it is uninitialized, but function "data" is now in context.
In MATLAB 7, you cannot use the same name in a single function as
both a function and a variable.
Error in ==> sIsomap at 15
D=distance(data, labels, alpha);
2：
还有个问题：labels如何定义？
alpha = 0.5;
K = 10;
load data.mat
D=distance(data, labels, alpha);
options.dims = [2];
[Y, R, E] = IsomapII(D, 'k', K, options);

data即是变量名称又是函数名称，但是作为变量没有初始化，D=distance(data, labels, alpha); 这里的操作数data跟dat文件名称重复了，不知道是不是这个问题．labels是什么类型的变量，你给个初始值不就好了么．
想学习isomap算法，能不能介绍什么书给我看看啊，谢谢，
