Share MATLAB Runtime Instances

What Is a Singleton MATLAB Runtime?

You create an instance of the MATLAB® Runtime that can be shared among all subsequent class instances within a component. This is commonly called a shared MATLAB Runtime instance or a Singleton runtime.

Advantages and Disadvantages of Using a Singleton

In most cases, a singleton MATLAB Runtime will provide many more advantages than disadvantages. Following are examples of when you might and might not create a shared MATLAB Runtime instance.

When You Should Use a Singleton

If you have multiple users running from a specific instance of MATLAB, using a singleton will most likely:

  • Utilize system memory more efficiently

  • Decrease MATLAB Runtime start-up or initialization time

When You Might Avoid Using a Singleton

Using a singleton may not benefit you if your application uses a large number of global variables. This causes crosstalk.
