Is LabVIEW MathScript Deterministic?

• Yes and No

– Developers can write deterministic MathScript code

– Need to test the application for jitter

• Some of the built-on constructs and operators• Some of the built-on constructs and operatorsintroduce jitter into the application

– Receive performance and memory comparable to G

– Jitter causes the performance to be non-deterministic
