Thanks to Prof.Chris Luengo and Sean De for their comments on my previous post. Their response really ignite my senses and it helped me to sit on the code for hours and increased my confidence. I'm grateful to them. With the errors they raised, I have completely changed the code. The only problem that I'm getting is that the edge is to thick. Please help me to overcome this problem. Thanks in advance.

I can not see the improved aspects in your code comparing to the one in Matlab

With the exception of preallocation and a few added comments, everything I said in my last comment still holds.
