Abstract: A mechanism for the rapid prototyping of code whereby a user selects a subsection of code and runs multiple evaluations on the selected code and altered versions of the code without first saving and naming the code subsection is disclosed. The selected subsection of code, referred to as a code cell, groups multiple lines of code together and evaluates them together. Output from the analysis is displayed to a user. Algorithms may be altered and variable values may be modified in-place as required to achieve an optimal result for the user. Once a desired version of the code is established, the code may be saved and then published in multiple user-selected formats with a single command. Each code cell in the program code may be used to generate a separate publication thus creating a narrative effect when sequentially viewing a grouping of the publications in the user-selected format.

Abstract: The present invention provides a method and system for stage evaluation of a state machine model. Two types of transitions are used: first-stage transitions and second-stage transitions for a two-stage evaluation. In one embodiment, top-down processing and bottom-up processing may be combined using a two-stage evaluation. First-stage transitions are used with top-down processing while second-stage transitions are used with bottom-up processing. Certain conditions are used to determine if a switch from one type of stage processing to another type of stage processing is needed.

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.

Abstract: The present invention provides a method and system for exception handling in an executable process executing in a concurrent computing environment. The present invention allows a user to interrupt the executable process at any stage of the computation without disconnecting the communication channel among the instances of the executable process. Additionally, the present invention also allows interrupting the concurrent computing process at any stage when an error occurs in the executable process or the communication channel without terminating the communication among the instances of the executable process. Upon notification of an interrupt request, each of the instances of the executable process in the concurrent computing environment flushes any pending incoming messages to return itself to a previous known state while maintaining the communication channel between the instances of the executable process.

Abstract: An exemplary embodiment may provide a repository for containing representations that represent a model or a portion of the model. A user may store the representations in the repository, for example, as functions. The functions stored in the repository may be shared and used for processing another model that includes a pattern performing the same or similar function as the representations stored in the repository. A checksum may be compared to determine an equivalent function in the repository. In a different embodiment, the intermediate representation of the pattern may be compared to determine an equivalent function in the repository.
