In that case, the direct evaluation using exp will be inaccurate, however there is a solution in MATLAB, in the form of expm1. Your function is passing xi to it but xi is numeric 0.25. exp(-0.25) is going to be a numeric result and you would then be taking numeric diff() of the scalar results, which is going to return [] because numeric diff() has to do with the difference between adjacent elements.
