Error in function ssdLayer

I'm getting the following error when I try to run function ssdLayers: ???

Undefined function 'ssdLayers' for input arguments of type 'double'.

This is my code.

imageSize = [300 300 3];
numClasses = width(vehicleDataset)-1;
baseNetwork = 'resnet50';
lgraph = ssdLayers(imageSize,numClasses,baseNetwork);

Thank you.

The function ssdLayers is introduced in R2020a, make sure that the MATLAB version you are using is R2020a and you have Computer Vision Toolbox installed.
