Dear all i new user using mathlab, i got some coding that related with my study but need to modified, some code had i changed, i am very wonder this code was trouble, i try to add some parameter but still problem anyone help me to understanding what they want?

please find the following errors

Reference to non-existent field 'T'. Error in PhysicalModel/getProp (line 686) p = state.(fn)(:, index);

Error in PhysicalModel>@(x)model.getProp(state,x) (line 711) varargout = cellfun(@(x) model.getProp(state, x), ..

The point is that we do not have access to the code that creates that variable, so that we cannot tell you why the variable does not have the T field. wModel is being created without a T field and you need to go back to the code that creates it to figure out why it has no T.
