optimizeRun() tutorial?

markbeck

Does anyone out there know of a tutorial that shows how to use the optimizeRun command (and supporting commands)?

I'm trying to create an ocean script for running optimizations, but when I try to run it I'm getting errors..

e.g.:  *Error* eval: undefined function - ocniOptVariables

Never heard of it, and it doesn't show up in the finder.

 Thanks,

Mark

  • Hi,

     In my experience, curve-fitting for optimization is most easily done simply by taking the difference of 2 waveforms, applying the abs() function to get the absolute value, measuring the maximum value (ymax) of the result and then create a goal for that number to be less than some small value (or to be minimized).  E.g. ymax(abs(sig1-sig2)) 

    There is also a function called "compare" in the calculator which allows you to specify an absolute and/or relative tolerance for comparing 2 waveforms and returns a waveform with zero value in the domain where the tolerances are met.  You can read about it in the "Calculator Functions" section of the Virtuoso Visualization and Analysis (ViVA) Tool User Guide.

     I hope this is useful.
