Abstract: A system obtains code that includes sequences of code; identifies, within a first sequence of code and based on obtaining the code, a first routine that, when executed, enables an array of values to be generated. The array of values is associated with a variable included within the first routine. The system determines whether the routine includes a particular term, and identifies, within the routine, a first identifier when the routine includes the particular term. The first identifier corresponds to a second sequence of code that identifies a first data structure that stores information that identifies one or more second routines. The system identifies, within the data structure, a second routine based on the particular term and a second identifier corresponding to the first routine; executes, using the variable, the second routine to generate a result; and outputs the result based on executing the second routine.

A model may include one or more logging points which process data, the data being stored in a log associated with the logging point. The logging point may request that a logging object store the data point. The logging object may include a reference to a vector for storing the data point.

The vectors may be compressed and/or made circular to achieve improved efficiency.

Abstract: A method and apparatus automatically determines equilibrium operating conditions of a system model. The automated method enables users of block diagram models of dynamic systems to utilize simulation to define operating conditions for linearization. The automated method further allows users to generate operating conditions during simulation instead of explicitly specifying them by hand or using trim analysis. In accordance with one example, the method of generating a linear time invariant model includes providing a system model. A user specifies at least one event at which a linearization analysis should be performed. A simulation of the system model is executed. The electronic device automatically performs the linearization analysis upon occurrence of the at least one event as the simulation is running. Output results are generated of the linearization analysis to form the linear time invariant model.
