Generation of code from a graphical model

摘要

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.

1. A non-transitory computer-readable medium holding instructions executable by a processor, the instructions comprising:
instructions that, when executed, cause the processor to:
interact with a graphical model that includes;
a block, anda connection representing a signal received by or output from the block, wherein:
the signal is associated with an attribute,the attribute represents a size or a dimensionality of the signal, andthe size or the dimensionality of the signal changes during an execution of the graphical model; andgenerate code from the graphical model, the generated code comprising:
code representing the connection, the code representing the connection implicitly conveying the size or the dimensionality of the signal,code representing the block, the code representing the block:
identifying that the attribute of the signal representing the size or the dimensionality of the signal is a variable attribute, andretrieving or setting the size or the dimensionality of the signal using the attribute at a plurality of times during the execution of the model, the retrieving or the setting occurring before reading information from the connection or writing information to the connection.
