Error while augmenting lidar data

while using the code :

cdsAugmented = transform(cdsAugmented,@(x)augmentData(x));

augData = read(cdsAugmented);

augptCld = augData{1,1};

augLabels = augData{1,2};

augClass = augData{1,3};

labelsother = augLabels(augClass=='other',:);

labelsPedestrian = augLabels(augClass=='Pedestrian',:);

helperDisplay3DBoxesOverlaidPointCloud(augptCld.Location,labelsother,'green',...

labelsPedestrian,'magenta','After Data Augmentation');

I am getting this error:

Error using matlab.io.datastore.TransformedDatastore/read

Invalid transform function defined on datastore.

Caused by:

Undefined function 'augmentData' for input arguments of type 'cell'.

Hi,

I am getting "Unrecognized function or variable 'cdsAugmented'." error while running the provided code.

cdsAugmented = transform(cdsAugmented,@(x)augmentData(x));

Unrecognized function or variable 'cdsAugmented'.

augData = read(cdsAugmented);
augptCld = augData{1,1};
augLabels = augData{1,2};
augClass = augData{1,3};
labelsother = augLabels(augClass=='other',:);
labelsPedestrian = augLabels(augClass=='Pedestrian',:);
helperDisplay3DBoxesOverlaidPointCloud(augptCld.Location,labelsother,'green',...
    labelsPedestrian,'magenta','After Data Augmentation');

The error message you are getting indicates that the transform function applied to the cdsAugmented datastore is calling an undefined function augmentData with an input argument of type 'cell'. The augmentData function needs to be defined before you can use it to transform the datastore.
