Description: In statistics, Isomap is one of several widely used low-dimensional embedding methods, where geodesic distances on a weighted graph are incorporated with the classical scaling (metric multidimensional scaling). Isomap is used for computing a quasi-isometric, low-dimensional embedding of a set of high-dimensional data points. The algorithm provides a simple method for estimating the intrinsic geometry of a data manifold based on a rough estimate of each data point’s neighbors on the manifold. Isomap is highly efficient and generally applicable to a broad range of data sources and dimensionalities.

Description: matlab 降维工具箱，最新版本。包含各类线性及非线性降维代码，lle,lpp,mvu,isomap,npe等皆在其中。-DRTOOL, by itself, creates a new DRTOOL or raises the existing
singleton*.
H = DRTOOL returns the handle to a new DRTOOL or the handle to
the existing singleton*.
DRTOOL( CALLBACK ,hObject,eventData,handles,...) calls the local
function named CALLBACK in DRTOOL.M with the given input arguments.
DRTOOL( Property , Value ,...) creates a new DRTOOL or raises the
existing singleton*. Starting from the left, property value pairs are
applied to the GUI before drtool_OpeningFunction gets called. An
unrecognized property name or invalid value makes property application
stop. All inputs are passed to drtool_OpeningFcn via varargin.
*See GUI Options on GUIDE s Tools menu. Choose "GUI allows only one
instance to run (singleton)".
