Please post a copy of the error message and the relevant part of the code. It is impossible to guess the reasons of the problems without knowing any details.

your variable f is not defined. What is regwht?

[krishna]

its defined before this line like this f=getdata(vid,1);

[krishna]

[Azzi Abdelmalek]

which regwht

[krishna]

if u want to see the code i will send

[Azzi Abdelmalek]

what did you get?

vid=videoinput('winvideo',1);
triggerconfig(vid,'manual');
set(vid,'FramesPerTrigger',1);
set(vid,'TriggerRepeat', Inf);
set(vid,'ReturnedColorSpace','rgb');
start(vid);
i=0;
num=zeros(1,2);
while(1)
  trigger(vid);
  f=getdata(vid,1);
  g=reg(f,125);
  g=imadjust(g,[0 1],[1 0]);
  g=imfill(g,'holes');
  w=strel('disk',15);
  g=imerode(g,w);
  g=imopen(g,w);
  %imshow(g);
  %disp('frame number:');
  %disp(i);
  [l num(1,mod(i,2)+1)]=bwlabel(g);
  if (num(1,1)~=num(1,2))
     disp('number of coins=');
     disp(num(1,mod(i,2)+1));
  end
  i=i+1;
end

[krishna]

this is the code in this i am getting error in g=reg(f,125)

[Azzi Abdelmalek]

I'am not following you, you said the problem is regwht(f,125) and now it's reg(f,125). I do not know if this code is yours, even it's not, you have to know what this code is doing. reg is a function from control toolbox which gives the gains K and L for regulator and estimator.

I have the same error whether reg(f,125) or regwht(f,125)
