The Matlab Programmers Guide for LCLS describes use of Matlab very much oriented towards LCLS users, but includes labCA tutorial, very light on Aida support (the Aida web pages should be consulted directly), LCLS beam synchronous data acquisition (though not including "linac" - SLC control system devices), LCLS camera acquisition etc. See Sergei for more details.
