How can I define a function within a loop?

Say I want to repeat this user defined function within a loop with , how can I do it? Each time I do it like below I get this message - "Function definition is misplaced or improperly nested."

 r=1;

 while(1)

     function y= myFunc (x)
        y= -(500000*r*x(1));
        r=r+1;
     end
      if (r>10)
       break;
      end
end

You just asked this same question, answered. What was wrong with the last answer, where I showed how to create a similar function in a loop?

I am sorry where did you show? and I have not asked this question before! :O

You seem to be misunderstanding the fundamental difference between defining a function and calling it. You define it once and can call it as many times as you like. I'm sure this is covered in the documentation on functions though to be honest I've never needed to look since I know what a function is and how it works.

There is no need to define your function inside the loop.

Do something like this instead:

r=1;
myFunc = @(x,r) -(500000*r*x(1));               % Anonymous Function
while(1)
    % DEFINE ‘x’ SOMEPLACE
    y = myFunc(x,r)
    r=r+1;
    if (r>10)
        break;
    end
end

See the section on ‘Anonymous Functions’ in the documentation on Function Basics.
