High Level MATLAB Applications

“MATLAB and MML allow accelerator physicists to perform simple tasks independent of the Controls Department”

“For more complex tasks, MATLAB and MML provide a good platform to collaborate with the Controls Department”

NSLS-II Physics Infrastructure & Matlab

Guobao Shen, Brookhaven National Laboratory

• The epics-pvdata project– pvData

• memory resident database – records have structured data– pvAccess

• New version of EPICS Channel Access– javaIOC

• An engine for record processing and optional support– pvService

• Service developed against pvData/pvAccess

The great integration project…

MATLAB for CLS Accelerator OperationsWard A. Wurtz, Canadian Light Source

• CLS relies on MATLAB and the MML for many tasks:– Online accelerator control– Offline data analysis

• Extensively use for tasks that do not involve the MML software
