Notation in This Manual

Notation in This Manual

Like the reference manual, this manual uses the following conventions:

Important ideas are italicized the first time they appear.
The names of C routines and parameters in the ILOG CPLEX Callable Library begin with CPX; the names of C++ classes in the CPLEX Concert Technology Library begin with Ilo; and both appear in this typeface, for example: CPXcopyobjnames() or IloCplex.
Text that is entered at the keyboard or displayed on the screen and commands and their options available through the Interactive Optimizer appear in this typeface, for example, set preprocessing aggregator n.
Values that you must fill in (for example, the value to set a parameter) also appear in the same typeface as the command but slanted to indicate you must supply an appropriate value; for example, set simplex refactor i indicates that you must fill in a value for i.
Matrices are denoted in two ways:
- In printed material where superscripts and bold type are available, we denote the product of A and its transpose like this: AAT. The superscript T indicates the matrix transpose.
- In computer-generated samples, such as log files, where only ASCII characters are available, we denote the product of A and its transpose like this: A*A'. The asterisk (*) indicates matrix multiplication, and the prime (') indicates the matrix transpose.
