Numerical Integration Toolbox MATLAB Toolbox for 1-D, 2-D, and n-D Numerical Integration The original 1-D routines were obtained from NETLIB and were written by Howard Wilson Department of Engineering Mechanics University of Alabama Box 870278 Tuscaloosa, Alabama 35487-0278 Phone 205 348-1617 Email address: HWILSON @ UA1VM.UA.EDU The rest of the routines were written by Bryce Gardner Ray W. Herrick Laboratories Purdue University West Lafayette, IN 47906 Phone: 317-494-0231 Fax: 317-494-0787 Email: gardner@ecn.purdue.edu These are the general purpose integration routines: quadg.m -- High accuracy replacement for QUAD and QUAD8 (1-D) quad2dg.m -- 2-D integration over a rectangular region quad2dggen.m -- 2-D integration over a general region quadndg.m -- n-D integration over a n-D hyper-rectangular region Use the other routines if you want a specific integration quadrature or specific order of integration quadrature. It is faster if you know that you need a 10th order integration quadrature to use it directly. If you use the above routines, the integration will be done with quadratures of several different orders until the results converge.
