Multiple integral is an important and difficult part in advanced mathematical teaching, especially in multiple integral＇s calculation ,which involves in the determination of integral domain and the sequence of exchange integral and so on. The Matlab software has more advantages in calculating numerical solutions to multiple integral, its function-library furnishs several functions for solving simple multiple integral. For complicated integral, Matlab is used to draw the integral domain for identifying the type of integral doman at first, then corresponding functions are used to calculate. Several different examples of double and triple integral are discussed in this paper by using Matlab, and the corresponding codes are given. The operation and demonstration of Matlab is convenient, it has more advantages in aiding multiple integral＇s teaching.
