Accept or Reject

I am trying to write a script that allows me to accept or reject data, so would ginput work for that?

Here is an example. I generate a random dataset, then I cycle through each subset of data and I enter an "A" for accepting the data OR a "R" to reject the data. At the end, a new dataset is created with only the accepted data.

data = rand(5,10);           % generate 5 rows of random data
indices = 1:size(data,1);    % initialize indices of data
figure;
for ii = 1 : size(data,1)
  plot(data(ii,:));
  [x,y,button] = ginput(1);
  if button == 97 % A - for accept
      disp('Input Accepted!');
  elseif button == 114 % R - for reject
      indices(ii) = 0;
      disp('Input Rejected!');
  else
      disp('Button not recongnized!')
  end       
end
indices = indices(indices~=0); % Remove indices that were rejected
new_data = data(indices,:); % Create new dataset with only accepted data

Yes. Search for "ginput" in your help navigator. You can even set it up so that pressing the button associated with "R" rejects the data and "A" accepts the data... though a quicker way may be to associate mouse button clicks with either rejecting or accepting data.

You can run some tests before hand to see what letters are associated with what button numbers. For example, hitting the "A" button when the blank figure pops up gives the following:

>> [x,y,button] = ginput(1)

x =

      0.52189

y =

       0.3348

button =

    97

Thank you very much...but how exactly would you set it up so that "R" rejects and "A" accepts?
