HAND_DATA, MATLAB programs which carry 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.

HAND_DATA is available in a MATLAB version.
CONVEX_HULL, a MATLAB program which demonstrates the computation of the convex hull of a set of 2D points.
HAND_AREA, a MATLAB program which estimates the area of a curve which outlines a person's hand.
MAPLE_AREA, a MATLAB library 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 library which reads an image of a maple leaf and extracts the list of pixels that form the boundary.
MESH2D_HAND, a MATLAB program which reads in a set of 59 points which outline a human hand, and calls MESH2D, which is able to create a fine triangular mesh of the region outlined by the points.
POLYGON, a dataset directory which contains examples of polygons.
TRIANGULATE, a MATLAB program which triangulates a polygonal region.
The CONVEX_HULL program demonstrates how the computation of the convex hull of the hand data.
The SPLINE program demonstrates how the X and Y hand data can be used to generate smooth spline functions X(T), Y(T) which can be plotted to yield a smooth looking curve.
The TRANSFORMATION programs demonstrate linear transformations applied to the hand data.
The TRIANGULATE program can be used to triangulate the hand.
