(error with GPOP2:Sample points must be unique )

Hi

I got message error: Sample points must be unique.

Error in interp1

Error in gpopsGuessRPMD

Error in gpopsSolveRPMD

Error in gpopsMeshShell

Error in gpops2

for my code format here:

  x(t)=nombers
     setup. bounds=bounds 
     setup.guess=guess
   .
   .
          out: gpop(t,x) %(use interpolation )
          

How to getback to uniqueness values with in using closed backage??

Hi Amirah Algethami,

My understanding is that the issue is due to duplicate sample points used in interpolation. You can fix this by using the "unique" function. This will remove any duplicates in your sample points and sort them.

A similar kind of issue has been addressed in the following MATLAB answer.

You can find more information on "unique" function in the following documentation.

Hope this resolves the issue.
