The line
% eleng=xr-xl;
should not be commented out. It should be
eleng=xr-xl;

You cannot run that code just by pressing the green Run button. When you just press the green Run button, MATLAB has no way of knowing where to look for values for xr and xl
You need to go to the command line and invoke the function passing in values, such as
result = fefll(0.3, 1.84)
