Function ‘helperBac​kScatterSi​gnals’ cannot be invoked

Hi, I try the example code in 'Pedestrain and Bicylist Classification using Deep Learning', but it gave error: 'helperBackScatterSignals' is used in Pedestrian and Bicyclist classification Using Deep Learning. Error in my_demo (line 4) [xPedRec,xBicRec,xCarRec,Tsamp] = helperBackScatterSignals(numPed,numBic,numCar);. And cannot see the source code of this function either. Is there any further information for this function? Thanks!
