In the data section you specify the data coefficients to be used in the model. These can be scalars, vectors, and even arrays of multiple dimensions. By defining the data coefficients separately, the actual model is free of numerical data and thus easier to maintain. Furthermore, by using the import feature you can store the data in a separate file and retrieve it when generating the input file.
Each data coefficient is given a separate name that is used throughout the model. There are two different types of data objects that MPL recognizes; data constants and data vectors. The following sections describe how both are specified.
