This error indicates that MATLAB doesn't recognize the 'helperPlotScalogram3d' as the name of a function on the MATLAB path.
One possible workaround would be to save the code (given below) of "helperPlotScalogram3d" in your current directory and rerun your script.
% This function is only intended to support this wavelet example.
% It may change or be removed in a future release.
[cfs,f] = cwt(sig,Fs);
sigLen = numel(sig);
t = (0:sigLen-1)/Fs;
