applyBoundaryCondition error on standard example

Trying to run a very basic code to apply boundary condition to a boundary value problem I get the following error:

Error using pde.PDEModel/applyBoundaryCondition (line 120)
Expected a string for the parameter name, instead the input
type was 'double'.

The code used is the first example of the documentation on applyBoundaryCondition:

model = createpde(1);
R1 = [3,4,-1,1,1,-1,-.4,-.4,.4,.4]';
g = decsg(R1);
geometryFromEdges(model,g);
applyBoundaryCondition(model,'dirichlet','Edge',1,'u',0);

What may be the cause of such a strange error? Using MATLAB version 2016a - academic use.

Hi Alex,

The syntax of applyBoundaryCondition you are using was introduced in MATLAB R2016b. You are seeing the error message, because you are using older version of MATLAB. You can either upgrade your MATLAB or use the syntax as documented in R2016a.
