The entire code is attached. Please check it out. I spent hours trying to figure the source of the mistake but could not get around it.

Hi Marwan
when correcting the following line
[mldln,conf1] = mle(xdata,'pdf',@pdfdln,'start',[mu,sig],'upperbound',[5,5], 'lowerbound',[0.1,0.1],'options',options);
[mldln,conf1] = mle(xdata,'pdf',@dln,'start',[mu,sig],'upperbound',[5,5], 'lowerbound',[0.1,0.1],'options',options);
then the function produces a histogram, no errors
Does it fix it?
if so would you please be so kind to consider marking my answer as Accepted Answer?

Thank you Walter. This was smart note that I immediately accept it. Together with the above suggestion by *John BG,* the problem is solved.
Thank you for your time and cooperation.

You have
[mldln,conf1] = mle(xdata,'pdf',@pdfdln,'start',[mu,sig],'upperbound',[5,5], 'lowerbound',[0.1,0.1],'options',options);
but pdfdln is not a function you define, and is not a Mathworks supplied function or any function I can find anywhere on the Internet.
