摘要： A method, performed by a computer device, includes obtaining an in-memory representation of computer code from a block step method of an executable model in a modeling application, wherein the computer code in-memory representation includes one or more variables. The method also includes identifying, from the one or more variables, a subset of persistent variables and determining if any of the one or more variables in the subset of persistent variables are state variables. When none of the subset of persistent variables are state variables, a block output method is generated based on the computer code in-memory representation and the one or more variables. When the subset of persistent variables includes a state variable, both the block output method and a block update method are generated based on the computer code in-memory representation and the one or more variables.

摘要： 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.

摘要： In an embodiment, a method of establishing directed relationships between states in a simulation is disclosed. The directed relationships may allow the simulation to proceed from an initial state according to two or more divergent behaviors. The simulation may merge if two or more behaviors result in states that are equivalent. The method may further allow a state of the simulation which has not been stored to be interpolated from one or more states that have been stored. In one embodiment, a system may receive a request to revert to a previous state, and the system may identify a saved state that is closest to the requested state. The system may simulate from the identified state to arrive at the requested state. In one embodiment, the simulation may be a hybrid simulation which is advanced in both discrete and continuous increments.

摘要： A system and method creates a plurality of different ring components for a referenced model included within a parent model. The ring components include values for one or more model-level, block-level, and signal-level attributes of the referenced model. One or more ring components are selected and assigned to the referenced model in the context of the parent model. During execution of the parent model, information from the selected ring component is accessed and used to control execution of the referenced model. During code generation for the parent model, information from the selected ring component is accessed and used to control the code generation process for the referenced model.

摘要： Business management methods for on-demand trial based marketing and sales are introduced. Using on-demand trial technology, usage metrics can be automatically generated by tracking the usage of specific products and corresponding duration. Usage metrics and other data are automatically processed to qualify and channel leads to pertinent categories in sales and marketing. The present invention facilitates a more directed effort to investigate leads and makes the information of customers available for follow-up that has higher prospective sales potential. The present invention may also be used to dispatch pre-release reports automatically to a vendor.
