摘要：
We discuss here the algorithms of TwoD, a MATLAB program for approximating integrals over generalized rectangles and sectors. Capabilities of the language are exploited to make TwoD very easy to use. Vectorization is exploited by a novel algorithm to make the program efficient and reliable. TwoD provides for moderate singularities on boundaries of the region. (C) 2008 Elsevier Inc.
