Error:Index exceeds matrix dimensions. when Loading .mat file

Dear All, I am facing a strange error when loading a .mat file. I have checked that the .mat exists (with exists) and the variable name is not part of problematic ones (i,j length etc.)

The point is, I can load it in the main, but not in the functions which are called by main.

Here is the code:

function [environment] = loadNetworkEnvironment(load,genValue,nodes,environment,plotting)
files=string();
files(1)=string([dynamicPath(),'DistrictHeatingModel\01 Network Data\01 Environmental Data\',load.var1,'.mat']);
files(2)=string([dynamicPath(),'DistrictHeatingModel\01 Network Data\01 Environmental Data\',load.var2,'.mat']);

    if true
      for i=1:1:length(files)

      % Check if file f exists
      if exist(char(files(i)),'file')==2
          % Derive variable properties
          s=whos('-file',char(files(i))); % yes s exists in run through
          % Load the file     
          [file]=load(files{i});% here is the problem, producing the mentioned error
          % Check if the file is consistent with the network data
          if length(file.([s.name]))==nodes
              load.(['var',num2str(i)])=file.([s.name]);
          else
              warning(['Loaded file: ',load.(['var',num2str(i)]),' shows different size than the network, variable is set constant to general value']);
          end
      else
          warning(['Loaded file: ',load.(['var',num2str(i)]),' data does not exist, variable is set constant to general value']);
          % Set variable to general value from environment
          environment.(char(load.(['var',num2str(i)])))=ones(nodes,1)*genValue.(['var',num2str(i)]);

      end

end

Please help me out with that, btw, also manual loading (double klick in the editor) produces the same error...

Thanks to all!

I'm facing the same issue with .mat files although they are only about 5KB. It works only if I clear the workspace and then load it, else it always gives me the same error. I use 3 .mat files, and if they are not loaded in a particular order, I get this error as well.

Would be super grateful to get some clarity on this issue.

                load.(['var',num2str(i)])=file.([s.name]);

is overwriting the function load with a structure named load . That is a problem because you are inside a loop.
