helperCWTTimeFreqPlot is part of the Wavelet Toolbox examples in R2015b and R2016a. If you have one of those installed then you can find it in
fullfile(toolboxdir('wavelet'),'wavedemo')

In R2016a, the demos that use this are CWTTimeFrequencyExample, FinancialDataExample, and PhysiologicSignalAnalysisExample
As of R2016b, wavedemo was replaced by Wavelet Toolbox Examples, https://www.mathworks.com/help/releases/R2016b/wavelet/examples.html
The Physiological signal example was replaced by
openExample('wavelet/PhysiologicSignalAnalysisExample')
which does not need the helper function due to improvements in the cwt function.

Just go to the folder that contains the PhsycologicSignalAnalysisExample and the function is there. Copy it to your working folder and voila!

Just to clarify, the helperCWTTimeFreqPlot() and helperCWTTimeFreqVector() functions can be found in the folder:
'path_to_matlab/MATLAB/Examples/wavelet/PhysiologicSignalAnalysisExample/'
