why does my program terminate

Hiwhile i run this program my programhangs on ,dont now why,can anyone help me please

Fuzzification
  [nu da]=xlsread('lymphoma dataset.xls')
  cl=xlsread('class.xls');
  for i=1:size(da,1)

Please format your code so we can read it (see http://www.mathworks.com/matlabcentral/answers/7885-tutorial-how-to-format-your-question).

And also be specific about "terminate"

Hi,

Insert breakpoints at each xlsread command and see if it is one of the xlsread that is causing the problem.

@Vineeth Kartha: Did you see that the question is 5.5 years old and that the OP did not reply to questions for clarifications? I assume he was not interested in a solution.
