@janhardo  watch equation 14 have two solution becuase ODE have degree two is like quadratic equation when have two root

@acer  i delete it , in case i undrestand more about hirota and post with more detail  i work on it and i don't know when i finish the work but my target is still remain  about finding best way for finding D-operator  of any NPDE. and indeed when i post a different one two just becuase contain hirota moderator delete my post becuase of that i did.
why there is any problem?

@acer  I have a habit that unless I see something, I can’t do it. What you’re saying is very easy, but I haven’t seen it.

@acer each time we get this problem we post here fixed for us , i watch your code and me is not have any different but your code run mine not . my maple don't have 1D it work for latex too so

@acer i can't see any different?

@acer i just ask one more question a new algorithm i find know with a lot of example included ,i have to post this one 

@acer so i need another space no one watch the comment 
please don't delete!

@acer I want to refine my question to make it more clear and focused. The topic remains the same, but I plan to rephrase it so that it's easier for someone to understand and provide a helpful answer. Once I get my answer, I'll leave. I'm not here to cause any trouble—just seeking clarity on my topic, can i delete this question and again post the new one? i don't have anychoice

@janhardo i just looking for undrestanding without coding my coding is bad, but ask question they will @mmcdara  already finish it and he now how wrok with structure and there is a lot people which now this structure ...

@janhardo i think it is usless, instead of this ask question there is a lot people which can help a lot 

@janhardo  i am not home to check you did it can this applying for all pde or not?

@janhardo if get notion of this it will be easy for apply for more dimension still solve remain but solving is better than this hirota i will post another equation you post some question too if just i am post it will be bad becuase deleting

@janhardo is so hard we can't hundle it easy

@mmcdara is satisfy just when is simple equation i apply for two other equation but not satisfy when f_tt apear in equation 

@janhardo if  you can test i have a lot example which is i am stuck really ? test some of them let see what will happen? i can't undrestand the pdf coding
