CTDLab Website
CTD-Lab is a library of Matlab routines for computing the maximum number of points (dots) on a graph belonging to one of the following classes:
- Convex graphs,
- Holder-2 graphs,
- Increasing graphs,
- Lipschitz graphs,
- Unimodal graphs,
as well as the maximum number of darts on a graph belonging to the following class:
- Holder-2.
A good way to get started with CTD-Lab is to run the illustratives examples collected in the subdirectory Demos/:
- convex_demo.m,
- h2_demo.m,
- inc_demo.m,
- lip_demo.m,
- unim_demo.m,
- darts_demo.m.
The names of the above scripts indicate their functionalities.
More details regarding this package can be found in the paper “Dynamic programming methods for `Connect the dots’ in scattered point sets” by X. Huo, D. L. Donoho, C. Tovey, and E. Arias-Castro (2004). This paper is still under revision, and should be available on the publication web page in a near future.
