User Libraries

Analytica User GuideUser-defined Functions and LibrariesUser Libraries

When you place functions and variables in a library, the library becomes available as an extension to the system libraries. Its functions and variables also become available.

There are two types of user libraries:

A library is a module within the current model.
A filed library is saved in a separate file, and can be shared among several models.

Creating a library

To create a library of functions and/or variables:

Create a module by dragging the module icon from the node palette onto the diagram, and give it a title.
Change the class of the module to library or filed library.
Create functions and/or variables in the new library or create them elsewhere in the model and then move them into the library.

Functions and variables in the top level of the library can be accessed from the Definition menu or Object Finder dialog. Use modules within the library to hold functions and variables (such as test cases) that are not accessible to models using the library.

Adding a filed library to a model

Add a filed library to a model using the Add Module dialog in Analytica's File menu.

Using a library

When defining a variable, you can use a function or variable from a library in any of the following ways:

Type it in.
Select Paste Identifier from the Definition menu to open the Object Finder dialog.
Select Other from the expr menu to open the Object Finder dialog.
Paste from the library under the Definition menu.

Example

Compare the way the Capm() function is displayed in the Object window (see Libraries) to the way it is displayed in the Object Finder dialog.
