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 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.
