  1. You might have a bug in your code.
  2. Your program might just take a long time to complete.
  3. You might have run out of memory and your program might be swapping to disk. When this happens, the whole system will get slow
  4. You might have a corrupt MATLAB installation.
  5. You might have an operating system problem.
  6. You might have hardware problems.

A common bug that Walter mentioned is an infinite loop caused by not having an iteration limit on a while loop so that the while loop never ends. ALWAYS have an iteration loop as a failsafe:
maxIterations = 1000000; % Or whatever you think the max will ever be
condition = true; % Or some other initialization...
numIterations = 0; % Loop counter
while condition && (numIterations < maxIterations)
% FIrst update condition somehow...
% Then update loop counter
numIterations = numIterations + 1;
end
if numIterations >= maxIterations
message = sprintf('Loop exited early because the maximum number of iterations (%d) was reached', numIterations)
uiwait(warndlg(message));
end
