The effect of this statement is to declare the parameter d and to specify its domain as the set of ordered pairs in the Cartesian
product of i and j. The values of d are also given in this statement under the appropriate heading. If there are blank entries
in the table, they are interpreted as zeroes.
As in the list format, GAMS will perform domain checking to make sure that the row and column names of the table are
members of the appropriate sets. Formats for entering tables with more columns than you can fit on one line and for entering
tables with more than two dimensions are given in Chapter Data Entry: Parameters, Scalars and Tables.

面向对象的GAMA API允许GAMS无缝整合到为交互提供适当类别的应用中。这三个面向对象GAMS API是.NET, Java
和Python与.NET framework 4 (Visual Studio 2010)、Java SE 5或更高版本以及Python 3.4, 2.7和2.6。
除了面向对象的GAMA API,还有级别(或级别) 的GAMS API,它们的使用要求有高深知识的GAMS组件库。
除了API, GAMS还提供智能链接到应用程序,如MS Excel, MatLab或R。用户可以在这个环境中继续工作,通过一个
API就可以访问GAMS所有的优化功能。这就允许应用中的模型数据和结果可以可视化和分析了。
