The method includes creating at least one resettable variable in a model within the graphical modeling environment, wherein the resettable variable is hierarchically scoped. The resettable variable is reset to a preset value before or during a subsequent invocation of a part of the model that contains the resettable variable. The graphical modeling environment may be a state diagramming environment or the graphical modeling environment may be a time-based graphical modeling environment.

Abstract: A class definition syntax that leverages the array and math-oriented nature of a dynamically typed array-based programming language is discussed. Some embodiments of the present invention provides a mechanism for using meta-data to define a class implemented in the dynamically typed array-based programming language.

Abstract: A device receives programming code, corresponding to a dynamic programming language, that is to be executed by a computing environment, and executes the programming code.

For example, an exemplary method includes providing a first marshalling function that receives a portion of information manipulated by the executable code and produces a presentation layer representation of the portion of the information. The presentation layer representation is compatible with a debugger that debugs the executable code. An exemplary method also includes debugging the executable code to produce a presentation layer representation of the portion of the information with the first marshalling function so as to display the presentation layer representation of the portion of the information to a user via a display device. The debugging also includes modifying the presentation layer representation of the portion of the information to produce modified information for use by the executable code, a device, or a user.

Abstract: A mechanism in a block diagram environment allows the modeling of an execution behavior of a block in a block diagram, where a user selects the execution behavior from a plurality of functions related to the block diagram and where the execution behavior of the block is performed when at least one model variable associated with the block satisfies a user-specified condition is disclosed. States and other internal data in the designated block are initialized upon the satisfaction of the user-specified condition. The illustrative embodiment of the present invention also allows the internal data to be reset upon the ending of the event, such as the modeled introduction or withdrawal of power. The execution behavior may be suspended and resumed multiple times during the simulation in response to multiple occurrences of the specified event. The present invention also allows for selected data to be exempt from the reset process so that the selected data is non-volatile.

Abstract: A device receives model information associated with a modeling application. The device determines first and second conflicting information in the model information. The first and second conflicting information describe different characteristics of a model described by the model information. The device formats the first and second conflicting information in a manner that designates the first conflicting information as a first variant of the model and the second conflicting information as a second variant of the model. The model, when executed with the first variant, behaves in a different manner than when executed with the second variant. The device provides the formatted first and second conflicting information to the modeling application, provides information that identifies the first and second variant, receives a user selection of information that identifies the first variant or second variant, and executes the model based on the user selection.
