Problems with Nested functions

having lots of trouble with my program, alot of them would be solved if I could use nested functions, however my program will not let me use nested functions. Why? and anyways around this?

Function startup 
load Exampledata.mat 
  function example
      disp('hello world')
   end 
end

something even this simple will not work! Error result is

Error using load Attempt to add "clims" to a static workspace. See MATLAB Programming, Restrictions on Assigning to Variables for details.

Error in program (line 3) load ExampleData.mat

Call LOAD with an explicit output instead. Not doing so is bad for many reasons in addition to the error that it's giving you here.

Function startup 

   S=load('Exampledata.mat'); 

    function example
        disp('hello world')
     end 

end

Thanks that seems to do the trick, however anytime I try and call a variable in Exampledata.mat it is now undefined?

[Matt J]

The variables are fields of the structure output S. You should access them through that.

Check if ExampleData.mat is in your current folder

dir ExampleData.mat
