beta分布的概率密度的matlab代码-LinePicking:几何概率问题的数字代码，特别是“线拾取”问题的密度函数

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 man/ - Documentation *.RD R documentation LinePicking.pdf A description of the formulas with references. mathematica/ -- Mathematical worksheets for deriving some of the formula inst/ - files that R package manager will ignore.
