Systems and methods for services for assisting programming are disclosed. The systems and methods can be used to, during edit time, for program code or data of interest, identify one or more services available to the program code or the data of interest, generating a context for the one or more services, execute code for the one or more services within the context to generate a result for each of the one or more services, analyze the result for each of the one or more services to select a subset of results based on criteria associated with the program code, the data of interest, or the one or more services, and offer, to a user, services corresponding to the subset of results or the subset of results as suggestions to facilitate further development of the program code or use of the data of interest.

Providing services for assisting programming

A device may provide a user interface element for display in association with a displayed document that contains code. The user interface element may be associated with at least one adjustable state. The device may determine, based on a user interaction with the user interface element, a selected state of the at least one adjustable state of the user interface element. The device may generate information based on the selected state of the user interface element. The device may store the user interface element, the selected state of the user interface element, and the information in association with the document.

Embedding user interface elements in documents containing code

An analysis tool analyzes a model to determine the digital effect of the model in a modeling or programming environment. With the analysis tool, a user can determine minimum hardware functionality needed to execute the software generated from the model. The hardware functionality may include the word size of the microprocessor that executes the software appropriately. The hardware functionality may also include the execution speed of the microprocessor executing the software. The hardware functionality may further include the functionality of other hardware elements, such as the word length of an Analog to Digital converter. The analysis tool enables a user to produce a system at a low cost while achieving necessary performance criteria.

System and method for digital effects analysis

Digital effects analysis in modeling environments

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.

Method for analysis of control systems

A method of manipulating a block diagram model with a plurality of graphical modeling components by defining an open loop anywhere on the block diagram model is provided. Graphical modeling components in series with the open loop may be automatically recognized and a plurality of parameters of the graphical modeling components in series with the open loop may be displayed on a display device. A user may simultaneously tune the parameters of the graphical modeling components in series with the open loop. Factorization points breaking the block diagram model in two disconnected parts may be identified in the block diagram model. A virtual graphical model may be generated by replacing a pattern of the graphical modeling components between two factorization points with a single graphical modeling component representing the pattern.

Modeling of control systems with open-loop representations and factorization of components

A device provides an interface for permitting a user to define a block diagram model that represents a system, linearizing at least a portion of the block diagram model, analyzing a linearization result of at least one block of the block diagram model to determine contribution information of the at least one block toward a linearization result of the block diagram model, and outputting information concerning a result of analyzing the linearization result.

Analyzing linearization of models in modeling environments

Method and systems for analyzing the linearization of a model in a modeling environment are disclosed. The modeling environment may provide tools for linearizing the model to generate a linear model. The modeling environment may also provide tools for analyzing the linearization of the model. The tools for analyzing the linearization of the model may inspect the linear model to determine whether the model is properly linearized. The results of the linearization may be provided to users so that the users are able modify the linearization result and have the model linearized again using the modified information.
