Abstract: Methods, system and computer program products are disclosed for providing a graphical modeling environment in which a graphical model is generated and executed. In the graphical modeling environment, elements are provided to define or describe signals associated with resources that are coupled to the graphical modeling environment. The high-level signal definition or description elements define or describe the signals associated with the resources regardless of the hardware of the resources. With the use of high-level signal definition or description elements, the users have the capability to deal with the signals transmitted to/from the resources without the specific knowledge of the hardware of the resources.

Abstract: The present invention provides a framework to let users systematically analyze, and design controllers for, complex non-linear dynamic systems modeled in a block diagram environment. By extracting linearized models from non-linear plant models (block diagrams), users can use one or more control design and tuning methodologies available for linear systems. Complex side effects, such as cross-coupling and exogenous disturbances, are viewable and can be dealt with in real-time during a design. The results of a design are automatically implemented in a block diagram.

Abstract: A method and apparatus, including a computer program apparatus, which facilitate invoking methods of objects defined within an object-oriented environment from an array-based technical computing environment often used in conventional mathematical tools. When a method is invoked from the computing environment, the techniques automatically compare the array input parameters with data-types accepted by methods defined within the object-oriented environment. Based on this comparison, the invention selects a method that best accepts the input arrays. The invention, therefore, allows a user to easily invoke methods from external objects, such as Java objects, directly from the technical computing environment of the mathematical tool.

Abstract: The illustrative embodiment of the present invention provides a method for extending a programming language to interact with foreign object systems. Through the use of an opaque interface, a requesting unit may interact with multiple foreign object systems. The requesting unit is an executable piece of code such as a script, applet or application. A single set of procedures written into the opaque interface and accessible by the requesting unit enable the requesting unit to interact with the foreign object systems. The foreign object systems register with the opaque interface. The registration process for the object systems includes the creation and registration of a defined set of functions, the format for which is provided by the opaque interface. The defined set of functions are called by the procedures in the opaque interface and execute in the object system.

Abstract: A method, system and computer program product is disclosed for providing a distributed computing environment in which an arbitrary job manager or scheduler is able to be employed. In the distributed computing environment, a job is created in a host or client to include one or more technical computing tasks and submitted to the arbitrary scheduler in a portable format. Since the portable format of the job is independent of the platform structure of the scheduler, the schedule can handle the job regardless of the platform structure of the scheduler. The scheduler then transfers the job in the portable format to one or more remote workers. The present invention utilizes a portable format to submit the job to a scheduler and to distribute the job to remote workers so that any scheduler can receive and distribute the job to the remote workers.

Abstract: Methods and systems for selecting multiple entities of a model or models to set or change data of the multiple entities together in a modeling environment are disclosed. When users create or edit a model or models, information on the entities of the model or models is provided to the users so that the users can select multiple entities in the model or models. On the selection of the multiple entities in the model or models, the modeling environment dynamically generates a user interface for the selected entities of the model or models for displaying, setting or changing data of the selected entities together. The user interface may display data of the selected entities that is not common to all of the selected entities in a different manner so that the users can identify common data of the selected entities.

Abstract: A computer system receives a description of a finite state machine including a temporal logic condition and generates code for emulating the described finite state machine.

Abstract: The present invention provides systems and methods which allow the translation of a first representation into an intermediate representation and then into a target representation. The first representation can take numerous forms, including a system model that contains hardware components, software components or some combination thereof. Additionally, the target representation can be in the form of a desired system implementation. The intermediate representation generated from the first representation can include both parallel and serial processes from the first representation. This intermediate representation then uses both serial and parallel processing techniques operating on the system model from within a single intermediate representation to translate the system model of the first representation into a target representation. The target representation may be in a format that is readily used in the creation of a system implementation by a user.

Abstract: A method and system are provided for generating code from a graphical model in a graphical modeling environment. The graphical model includes at least one signal having a data size, a data dimensionality, or both that can vary from a first time instance to a second time instance as the model executes. The size and dimensionality of the signal can vary without the use of a graphically rendered connection to convey the size and dimension information to a block associated with the signal. The generated code includes the attributes of the signal.

Abstract: Methods, systems and computer program products are disclosed for automatically generating hardware description language code from a model. The hardware description language code may be generated from a graphical program/model, such as a block diagram model. The hardware description language code may also be generated from a text-based program/model, such as a model created using MATLAB® tools. In particular, the present invention provides for the automatic code generation of an interface between components in the model. The present invention may provide options for selecting at least one of multiple types or styles of the component interfaces in the model. The selection of the interface types or styles may be controlled by the user or inferred by other parameters, such as implementation parameters.

Abstract: A method of integrating freehand user input into a block diagram environment is disclosed. The freehand user input is a user's approximation of a diagram component or feature of a component which is received by the block diagram environment and compared to multiple patterns stored in a storage location. The storage location holds patterns of block diagram components and block diagram component features. The freehand user input may be displayed, superimposed on a block diagram being shown to the user. Upon the freehand user input being matched to one of the patterns representing a block diagram component or feature of a component, the freehand user input is replaced on the displayed block diagram with an electronic device drawn rendering of the matched diagram feature component or feature of a component. Partial matches of the user drawn input may result in a menu of choices being presented to the user for selection.
