Point3 method error when running SFMExample.m

I am using Ubuntu 16.04 + Matlab 2017b. I have built and installed GTSAM with matlab toolbox by following the readme file. The error I came across when running SFMExample.m is as below:

No appropriate method, property, or field 'retract' for class 'gtsam.Point3'

point_j = Point3(truth.points{j}.vector() + 0.1*randn(3,1));

instead of retract to initialise the points
