Reference to non-existent field

Question

0 个投票

Can someone tell me what's wrong with my classdef? When I run cool_class.funk(x) it works fine. But for cool_class.Afunction, it returns reference to non-existent field. I'm new to object, and it doesn't really make sense.

classdef cool_class
    properties
        tdata=[];
        adata=[];
        ainterp=[];
        tinterp=0;
    end
      methods (Static)
          function y = funk(x)
              y=0.5*x.^2+4;
          end
          function output=Afunction(z)
              %load shortdata.txt
              %tdata= shortdata(:,1);
              %adata= shortdata(:,2);
              xq1=0:0.01:z;
              vq1=interpn(cool_class.tdata,cool_class.adata,xq1,'linear');
              output.ainterp=vq1(end);
          end 
      end
end
