How to run MATLAB in multi-corner sims and have it return values to ADE

Hi all,

 I have a MATLAB script that I would like to post-process some waveforms after running transient simulations.  I have been able to create matlabexpr and MATLAB *.m file that correctly runs and return the values I want, but it only works if I am running a single corner in my sims.  I expect my syntax is incorrect in how I am passing information to and from MATLAB when there are multiple corners / points being simulated, I have looked at the RAK on using MATLAB like this already.  I cannot post my code, but could someone please post code that does the following:

1) in maestro / Outputs Setup: create a normal expression output something like:   

   wave_out = lshift( clip( v("/clock" ?result "tran") 1n VAR("t_end") ) 1n )   

(this is clipping a transient waveform and left-shifting it to re-set the x-axis, where t_end is a Design Variable).

2) there are also scalar Output Setup results, say:

   num_periods = 10

   end_time = VAR("t_end") / 2

3) create a matlabexpr, per point (for every Corner being simulated) that calls for a *.m file that reads in num_periods and end_time and wave_out, does a calculation on them, and returns to ADE. 

In pseudo-code it would look something like this:

In Cadence - Outputs Setup:

 myresults = matlab_file()

 calc1 = myresults.results1

 calc2 = myresults.results2

 calc3 = myresults.results3

The *.m file, matlab_file.m, would be something like:

function results = matlab_file()

  <import required Cadence stuff>

 num_periods_matlab = <read in the Cadence output result num_periods, a scalar>

 end_time_matlab = <read in the Cadence output result end_time, a scalar>

 wave_out_matlab = <read in the Cadence output result wave_out_matlab, a Cadence-constructed waveform and not a scalar>

 results = struct('results1', end_time_matlab / num_periods_matlab, 'results2', ymax( wave_out_matlab ) / num_periods_matlab, 'results3', wave_out_matlab * wave_out_matlab )

end

My pseudo-example above is obviously not doing much, but with a posted *.m file solution here I will learn the proper syntax about loading in both scalars and constructed waveforms from Cadence to MATLAB.  This should work and evaluate properly if, in my Interactive.10 simulation, I am running over various values of t_end (5n:1n:10n), over temperatures, over ... Corners.  I believe what I have right now is incorrectly doing the first four lines of my fake function above, which leads to 'error' or 'eval error' if I run more than one Corner.  

Thanks very much in advance,
