MATLAB: How to define a function within a loop

MATLABmatlab function

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

Best Answer

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
