@nm  How we can add more parameter  by limit or anything else becuase there is a lot method used this technique if i can find for example at lease 100 parameter whcih give me solution this is a big achievment, i get idea from your comment so we can replace the parameter by another parameter by get limitng the result will change or not?  for example in first row m->1 (left) we can say m->2 right, what will happen to solution it will change or it will be error, how we try this? we must find thus solution even if we don't have thus data and find more solution?

@nm i will add another one question of this kind  topic again with new idea please help me in next question, i will mention you.

@janhardo  nevermind i got idea i was wrong in third part

@janhardo  that is all i find all step in last file but i want make it easier and this equation is easy one i want update the code for the hard equation and there is a lot of method i wnat apply the code for all of them... and this part by @dharr  is so good and work for me i don't have issue but when we done this  i figure out is just for one case which is A,B not zero but if in begin our auxilary A at there is zero then our system of equation will change and out come of case will change  it almost done all part we just one collect them and get out come

@nm open please 

@janhardo this code is emazing and different   and determine all cases one by one but i am looking for U(xi) and list them for each case for example A=0 the U(xi)=@ my mean not G(xi) also if do testode for each case it will be emazing, i upload in top and i will upload here too if provide me this it will be emazing

@dharr first thanks for this code
there is one case missing which is A  and B not equal to zero !
also i am  looking for U(xi) with telling me when for example A=0  then U(xi)=@  with substitute case in U(xi), also i need to clarify the odetes, i know it is work but want be sure for substitute odetest must be zero,  i am sure you didn't see this file i upload later 

i hope undrestand my mean

@Kitonum it seems you have a good expreince in changing variable always i have problem in physic how we can remove the absolute value automatically i do that by hand in equation where  q=U(x)exp(I*x) then |q|=U(x) and |q|^2=U(x)^2 how maple do that automatically and do the change variable all by programing something like that in below picture also i have esier   if needed i just want to know how  replace this absolute value and do that automatically without need hand 

@acer  it is imposible for each equation i do the that i must update version i hope that is work 

@acer i saw you use kernelopts but now work my maple is like that back to orginal

it is same when i apply

@nm thank you for this new code

@acer  sorry for late, if i use 2024 version this problem will be fix? and my code of 2021 is work or not?  becuase i have a lot of this problem i can't use this code to all my function the editore of journals   give us comment which we must change all of this outcomes to shorter and i must change all my outcomes it take a 2 or 3 day to change all of them.

@acer thank you so much

@acer i have the problem with your last exploring graph  please help for upgrading it  i will send you in email if possible ...
