LinePicking

Numerical code for geometric probability problems, in particular density functions for the "line picking" problem, i.e., what is the length of a line picked at random from some region.

Details:

src/

LinePicking.h

    Contains C library routines to compute the densities for "line
    picking" problems on various regions.

beta.h: has required incomplete and complete beta functions
  LinePicking_test.m: has Matlab test scripts, which
  also generate nice plots of the distributions

LinePicking.c

    Contains bridges to allow the routines in .h to be called from
    another C program, Matlab (through MEX) and eventually through R.

Matlab/ - Matlab wrapper functions and compilation rules

LinePickingXXX.m

   Callbacks to the MEX routine for various functions.

LinePicking_test.m

   Matlab code to show how to call the MEX routines, and to test
   out various cases, compute Laplace transforms, and draw plots.

LinePicking_test_sim.m

   Matlab code to compare calculated distributions with simulations.

LinePicking_numerical.m

   A comparison of exact computations with simulation-based
   estimates.

R/ - R wrapper functions and compilation rules

LinePickingPDF.R

  R wrapper function

LinePicking_test.R

  Example of how to call the function in R
