    • A method, performed by a computer device, may include interacting with one or more plots associated with a simulation of an executable graphical model, receiving a selection of one or more target output points associated with the one or more plots; receiving a selection identifying one or more parameters, associated with the one or more plots, of one or more system parameters, associated with the executable graphical model; and generating an inverse parameter Jacobian matrix. The inverse parameter Jacobian matrix may correspond to an inverse of a parameter Jacobian matrix that relates one or more partial derivatives of the one or more system parameters to one or more system equations. The method may further include determining one or more tuning values for the selected one or more parameters based on the generated inverse parameter Jacobian matrix and based on the selected one or more target output points.

    • A method, performed by a computer device, may include receiving a request to automatically select a solver for a simulation of an executable graphical model, determining a Jacobian matrix for the executable graphical model, calculating a stiffness of the executable graphical model based on the determined Jacobian matrix, and determining whether the calculated stiffness is greater than a stiffness threshold. The method may further include automatically selecting an implicit solver as the solver for the simulation, in response to determining that the calculated stiffness is greater than the stiffness threshold, automatically selecting an explicit solver as the solver for the simulation, in response to determining that the calculated stiffness is not greater than the stiffness threshold, and performing the simulation using the selected solver.

    • A technique for analyzing a model, either statically or dynamically, checks the model for one or more specified patterns with respect to accessing a data store associated with the model. The patterns may include, for example, writing to the data store prior to reading the data store, reading the data store prior to writing to the data store, writing to the data store multiple times prior to reading the data store, reading the data store multiple times before writing to the data store, etc. The model may be an executable graphical model that is generated in a graphical modeling environment. A result may be generated based on analyzing the model and the result may be output.
    • 一种用于分析模型(静态或动态)的技术来检查模型对于访问与模型相关联的数据存储的一个或多个指定模式。 模式可以包括例如在读取数据存储之前写入数据存储器,在写入数据存储之前读取数据存储器,在读取数据存储器之前多次写入数据存储器,读取数据存储器 在写入数据存储之前多次等等。该模型可以是在图形建模环境中生成的可执行图形模型。 可以基于分析模型生成结果,并且可以输出结果。

    • 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.
    • 公开了用于选择模型或模型的多个实体以在建模环境中将多个实体的数据设置或改变在一起的方法和系统。 当用户创建或编辑模型或模型时,将为模型或模型的实体提供的信息提供给用户,以便用户可以在模型或模型中选择多个实体。 在模型或模型中选择多个实体时,建模环境为所选择的模型或模型实体动态生成用户界面,用于将所选实体的数据显示,设置或更改在一起。 用户界面可以以不同的方式显示所有被选实体不共同的选定实体的数据,以便用户可以识别所选实体的公共数据。
