MATLAB: How to get print statements to show up in Console Window of deployed *.exe App

debuggingdeployed appsMATLAB Compiler

Folks,
I am trying to debug a problem that only occurs in a deployed version of a Matlab GUI. The console window that is running when the *.exe GUI is executed will not show my executions like this:
a = 3
sprintf('hi jack = %d', a)
However, it will show
'This is a test'
This of course makes debugging problems in a deployed *.exe challenging. Can anyone offer workarounds or knowledge about best practices for debugging deployed apps?
Here is specific code:
function [o, oc] = GetASPMPOutputClone(tc, pc)
'sleeping 1 sec'
pause(1)
o = calllib('ASPMP64', 'AllocateOutputASPMP', tc, pc);
oc = get(o, 'value');
'sleeping 1 sec: b'
pause(1)
nRange = tc.nRange;
nTime = tc.nTime;
setdatatype(oc.slowSemb, 'doublePtr', oc.nSlowSemb, 1);
setdatatype(oc.timeSemb, 'doublePtr', oc.nTimeSemb, 1);
setdatatype(oc.rawCoherenceMap2D, 'doublePtr', 4*oc.nSlowSemb*oc.nTimeSemb, 1);
setdatatype(oc.finCoherenceMap2D, 'doublePtr', 4*oc.nSlowSemb*oc.nTimeSemb, 1);
setdatatype(oc.finBeamMap2D, 'doublePtr', 4*oc.nSlowSemb*oc.nTimeSemb, 1);
setdatatype(oc.finSNRMap2D, 'doublePtr', 4*oc.nSlowSemb*oc.nTimeSemb, 1);
setdatatype(oc.waves, 'doublePtr', nRange*nTime, 1);
sprintf('nRange, nTime = %d %d', nRange, nTime);
'sleeping 1 sec: c'
pause(1)
setdatatype(oc.wavesInstAmp, 'doublePtr', nRange*nTime, 1);
setdatatype(oc.wavesInstFreq, 'doublePtr', nRange*nTime, 1);
setdatatype(oc.wavesMaxCoh, 'doublePtr', nRange*nTime, 1);
setdatatype(oc.wavesOptSlow, 'doublePtr', nRange*nTime, 1);
setdatatype(oc.wave, 'doublePtr', nTime, 1);
setdatatype(oc.waveEnv, 'doublePtr', nTime, 1);
setdatatype(oc.detector, 'doublePtr', nTime, 1);
setdatatype(oc.shortTermAve, 'doublePtr', nTime, 1);
setdatatype(oc.longTermAve, 'doublePtr', nTime, 1);
setdatatype(oc.timeWinBeg, 'doublePtr', 4, 1);
setdatatype(oc.timeWinEnd, 'doublePtr', 4, 1);
setdatatype(oc.slowWinBeg, 'doublePtr', 4, 1);
setdatatype(oc.slowWinEnd, 'doublePtr', 4, 1);
setdatatype(oc.timePicksObserved, 'doublePtr', nRange, 1);
setdatatype(oc.timePicksQuality, 'doublePtr', nRange, 1);
setdatatype(oc.timePicksEstimated, 'doublePtr', nRange, 1);
'sleeping 1 sec: d'
pause(1)
setdatatype(oc.variableDensityLayerRaw1D, 'doublePtr', 4*oc.nSlowSemb, 1);
setdatatype(oc.variableDensityLayerFin1D, 'doublePtr', 4*oc.nSlowSemb, 1);
setdatatype(oc.variableDensityLayerRaw1DUpSampled, 'doublePtr', 4*oc.nSlowSembUpSampled, 1);
setdatatype(oc.variableDensityLayerFin1DUpSampled, 'doublePtr', 4*oc.nSlowSembUpSampled, 1);
sprintf('nSlowSemb = %d', oc.nSlowSemb);
sprintf('nSlowSembUpSampled = %d', oc.nSlowSembUpSampled);
'sleeping 1 sec: d2'
pause(1)
setdatatype(oc.slowPicks,'doublePtr', 2, 1);
setdatatype(oc.slowPosErrorPicks,'doublePtr', 2, 1);
setdatatype(oc.slowNegErrorPicks,'doublePtr', 2, 1);
None of the sprintf statements get displayed. Nor will any "a = 1" statements if I put them in. The whole app catches a throw when it gets to the "setdatatype(oc.slowPicks" line, reporting:
Undefined function 'setdatatype' for input arguments of type 'double'.
This post is not about this particular error, but about how to debug in the *.exe environment.
Thank you, Kristoffer Walker

I have found an answer that helps from another post. Execute the *.exe from within the Matlab GUI window. This enables some of the previously hidden print statements to be displayed in the Matlab GUI console window.
