Patent number: 9710242Abstract: A method and apparatus, including a computer program apparatus, which facilitate invoking methods defined within a second language system from a first language system. When a method is invoked from the first language system, the techniques automatically compare the output parameters of the first language system method with the number and data-types of parameters output by methods defined within the second language system. Based on this comparison, the invention selects a method that best matches the output signature of the invoked method. The invention, therefore, allows a user to easily invoke methods from external objects, such as C# objects, directly from the first language system.Type: GrantFiled: September 30, 2010Date of Patent: July 18, 2017Assignee: The MathWorks, Inc.Inventors: Fazil Peermohammed, David A.

Patent number: 9600411Abstract: A system and method determines an object's lifetime. An object lifecycle engine may work with an object oriented environment. As objects are created, an object graph may be constructed having one or more roots. A root record graph may be constructed, and edges of the root record graph may point in an opposite direction than the edges of the object graph. As objects, entities, and references are added, removed, or deleted from within the environment, the object graph and the root record graph may be updated. A root finder may search the root record graph to determine whether a given root record is no longer rooted. If a root record is no longer rooted, then the object associated with that root record may be determined to be unreachable and at the end of its lifetime. If the root finder search is performed when references are removed, then objects may be destroyed in a deterministic manner.Type: GrantFiled: March 31, 2011Date of Patent: March 21, 2017Assignee: The MathWorks, Inc.Inventor: David A.

Patent number: 9146750Abstract: 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.Type: GrantFiled: August 10, 2012Date of Patent: September 29, 2015Assignee: The MathWorks, Inc.Inventors: Thomas Albert Bryan, Julia Palmateer Wall, David A.
