Abstract: A method and apparatus for retrieving selected information in a graphical model environment originates with the provision of the graphical model environment. The selected information is selected by, or provided to, a block diagram simulation application operating the graphical model environment. The selected information can be in the form of data or a reference to data. The selected information is automatically incorporated into the graphical model environment.

Abstract: A mechanism for converting a graphical model of a system into an intermediate representation (IR) of a model is discussed. The mechanism alters the IR, and uses the altered IR to create a new or updated graphical model of the system that may be viewed and simulated by a user. Once the user is satisfied with the alterations to the IR, the IR or the graphical model may be used to generate code in a target language to enable the building of the physical system being designed. The use of the altered IR to generate a new or updated graphical model allows a more efficient and customizable design and simulation process than is typically found by simulating code that has been converted to target languages. The generation of the graphical model based on the altered IR allows a user to visually inspect the changes to the system, and the simulation of the graphical model based on the altered IR allows corrective action to be taken to account for any changes that occurred during the transformation of the model.

Abstract: In one embodiment, a computer-implemented method for concurrently processing at least a portion of a graphical model is provided.

Abstract: A remote auxiliary tool is created in a graphical model having at least one of a signal or a block. The remote auxiliary tool is non-intrusively attached to one of the signal or the block. The graphical model and the remote auxiliary tool are executed synchronously. At least one of an execution result or a remote auxiliary tool result is output to at least one of a display device, a storage device or a destination device.

Abstract: Remote auxiliary tools are provided for non-intrusively and synchronously interacting with graphical models. The remote auxiliary tools are non-intrusively connected to the graphical model without requiring the addition of components to the model definition. The remote auxiliary tool can operate in an observer mode, a bypass mode, and/or a generator mode. In these modes, the remote auxiliary tool can synchronously read, modify, and/or generate data, respectively, in response to events within the executing block diagram.

Abstract: Exemplary embodiments update a revision value related to a data set that includes data. The revision value indicates whether a revision event has occurred with respect to the data set. Exemplary embodiments identify whether a change associated with the data qualifies as a revision event in the data set. The identification is based on a configurable requirement. The revision value is specified based on the identification to provide a user with an indication of whether the revision event has occurred.

Abstract: Remote monitoring tools are provided for non-intrusively and synchronously interacting with graphical models. The remote monitoring tools are dynamically connected to the graphical model without requiring the addition of components to the model definition. The remote monitoring tool can perform dynamic range assessment on the graphical model.

Abstract: A mechanism for using stream objects in stream processing operations is provided. A definition of a class of stream objects used in stream processing algorithms can define output and update operations included in instances of the stream objects and the API (application programming interface) through which they may be called. The class definition may further include the type of state information to be held by the instantiated stream objects. An instance of the stream object may be instantiated in a text-based computing environment and the operations may be used to process streams of data.

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.

Abstract: A system is configured to: conduct asynchronous updates, of a display, based on a fixed rate when operating in an asynchronous state; determine whether to switch to a synchronous state from the asynchronous state based on the asynchronous updates; conduct synchronous updates, of the display, after switching to the synchronous state; receive a lock request, and conduct updating of the display based on the lock request. The synchronous updates may be performed independent of the fixed rate.

Abstract: A modeling system includes a graphical programming environment that receives a first graphical model from a user. The system may also receive a configuration control set for the first graphical model. A code generation engine converts the first graphical model into an intermediate representation (IR). A second graphical model is created from the IR and the configuration control set. The second graphical model is displayed to the user, and may be subject to one or more modifications. Code in a target language may be generated from the second graphical model.

Abstract: In one embodiment, a processing block of a block diagram receives input data including a plurality of data elements organized as a matrix of a first size. At least a portion of the input data is partitioned into a plurality of data blocks in response to user-selected parameters. A data block includes selected ones of the plurality of data elements organized as a matrix of a second size. The data processing block performs a data processing function on the plurality of data blocks in a user-specified order to yield processed data corresponding to each data block. The processed data corresponding to each data block is then reassembled to form output data corresponding to the input data and the output data is output from the processing block to another block of the block diagram.
