hand_data, a MATLAB code which carries out some numerical exercises based on data that came from tracing several points on a person's hand.

The original proposer of this exercise was Cleve Moler, in the textbook Numerical Computing with MATLAB.

Related Data and Programs:

convex_hull, a MATLAB code which demonstrates the computation of the convex hull of a set of 2D points.

hand_area, a MATLAB code which estimates the area of a curve which outlines a person's hand.


hand_mesh2d, a MATLAB code which reads in points which outline a human hand, and calls mesh2d(), which creates a fine triangular mesh of the region outlined by the points.

human_data, a MATLAB code which starts with an image of simple outline of a human body, tabulates a sequence of points on the outline, creating numerical data defining the boundary. It is then able to fill the region with mesh points and triangulate the region. This allows the region to be analyzed by the finite element method (FEM).

maple_area, a MATLAB code which takes the list of pixels that form the boundary of the image of a maple leaf within a picture, and uses grid, Monte Carlo, and Quasi Monte Carlo sampling to estimate the area of the leaf.

maple_boundary, a MATLAB code which reads an image of a maple leaf and extracts the list of pixels that form the boundary.

polygon, a dataset directory which contains examples of polygons.

triangulate, a MATLAB code which triangulates a polygonal region.
