| − | When calling a function in Analytica, you can use the conventional method of listing parameters in their standard sequence, or named-parameter syntax, where you type the parameter name, followed by a colon (:), followed by the parameter value. Here is an example:

| + | * [[:Category: Optimization Functions]] |
| − | Decisions: [d1, d2],
| |
| − | Constraints: [c1, c2, c3],

| − | Maximize: x)</nowiki>
| |
| | | | |
| − | Since [http://wiki.analytica.com/index.php?title=DefineOptimization DefineOptimization]() has a large number of optional parameters, named-parameters are much more convenient to write and read. So, we use that method in our examples.

| − | Optimization status functions can reveal important details such as the selected engine matrix coefficients, and other information that may be helpful with troubleshooting. These functions are:
