See picture for details.

I'm running Matlab 2015b with pde toolbox, yet some functions from that release (eg. interpolateSolution) are missing. Functions that were introduced earlier in this toolbox work fine. Any ideas what I can do to use these new functions?

Cheers

Doug

interpolateSolution &nbsp is obviously a method of three different classes

&nbsp

thus the first argument of the call must be an instance of one of those classes.

And those classes are in the package, pde.

Added later

9.0.0.341360 (R2016a)

Sorry, I didn't consider the fact that the function may have changed between the release you were using and the current release whose documentation I was reading.

Looking at the examples on the documentation page for interpolateSolution in release R2015b you will need to create a results object using createPDEResults and pass that object into interpolateSolution. Using the example from the documentation for pdenonlin:

% Create and set up the model
model = createpde;
geometryFromEdges(model,@circleg);
a = 0;
f = 0;
c = '1./sqrt(1+ux.^2+uy.^2)';
boundaryfun = @(region,state)region.x.^2;
applyBoundaryCondition(model,'Edge',...
  1:model.Geometry.NumEdges,...
  'u',boundaryfun,'Vectorized','on');
generateMesh(model,'Hmax',0.1);
% Solve the PDE
u = pdenonlin(model,c,a,f);
% Create the results object
results = createPDEResults(model, u)
% Interpolate the solution
IS = interpolateSolution(results, ...
  -0.5:0.125:0.5, ...
  -0.5:0.125:0.5)
