it is difficult to provide detailed help. I can only suggest that you read the help for the command

StringTools:-DecodeEntities()

to see if it meets your requirements

maybe something like the attached?

  h:= x->`if`( type(x, numeric),
               piecewise( x<=0,

Although the CUDA help page states (my emphasis)

The CUDA package allows Maple to use the graphics processing unit (GPU) of your NVIDIA(R) Compute Unified Device Architecture (CUDA)-enabled hardware to accelerate certain LinearAlgebra routines.

However if you check the page referenced as

the Routines Accelerated by the CUDA Package help page.

You will find that it contains precisely one entry, namely MatrixMatrixMultiply(). I take this to mean that any time one uses a high-level command for the LinearAlgebra() package which contains a matrix multiplication operation, then that operatio will be "CUDA-accelerated".

When I try this on my own machine running the multiplication example on the CUDA help page, then everything *seems* to work, although the CUDA-acceleration is not significant. In fact I obtained tNoCUDA := 1.813 and tCUDA := 1.880. On the assumption that I needed a "bigger" problem with "bigger" matrices so that the cost of setup/retrieval etc did not dominate the actual multiplication, I doubled the matrix size to 8000 - and tried the help page example again and promptly got a (temporary) black screen followed by a pop-up stating display driver error!!!

Now I'm prepared to admit my (Nvidia) graphics card is pretty old (2047MB NVIDIA GeForce GTX680), although the drivers are up to date.

Maybe in order to obtain significant benefits from GPU processing I need a newer card, with more cores and significantly more vram? I have been promising myself a whole new computer for quite some time now, but just haven't got around to building one

 

 

other than the "large" file takes a while - see the attached

So you are probably going to have to expalin what you mean by "consistency"

when I explained how to do this manually by pointing to the reference

https://www.mapleprimes.com/questions/229832-Phyysics-Updates-Installation

I'm going to try to make things really easy You have a directory called "C:\Users\jm\maple\toolbox. In order to update to the latest/greatest Physics udates, this directory needs a (valid) folder structure which looks like

2020
           PhysicsUpdates
                                       lib
                                             override_maple.txt
                                            
Physics Updates_1592550562672.maple                                      
                                       version.txt

Attached to this message is a zip file which 'starts' with the folder called '2020'. All you have to do is to unzip it to your directory "C:\Users\jm\maple\toolbox, in order to produce the following directory structure

C
    Users
               jm
                    maple
                               toolbox
                                            2020

                                                     PhysicsUpdates

                                                                                  version.txt

 

If you manage to achieve this then everything should just "work".

Should the Maple update process be able to achieve this? Obviously yes. However it seems that it is very good at sticking up assorted html subwindows, progress bars and all sorts of other irrelevant crap. Jusr very bad at the basic task of putting the right effin files in the right effin place :-(

Good luck!

there is no way to (directly) access Sage from Maple. (obviously one could probably do it with system calls, but this generally gets very untidy, very quickly)

A better approach may be just to write the necessary code within Maple.

I don't know anything about "Topological indices in Graph theory" - but the definition of the Wiener index, given here

https://en.wikipedia.org/wiki/Wiener_index

seems pretty trivial to implement, using commands from Maple's Graph Theory package. (Not sure about other topological indices - I didn't check)

The attached (correctly!!) computes the Wiener index for the two examples given in the above Wikipedia article

Well - if I fix the syntax errors, and then remove all references to parameters which are never used anywhere in your ODE system, but you want optimal values for (neat trick if you can do it!?), then allow for the fact that the Optimiser might attempt to use parameter values for whihc the dsolve() operation cannot find a meaningful solution etc, etc, etc, I can eventually come up with the attached - whihc does produce an "optimal" solution. However looking at the size of the residual error, I have doubts about how useful/relevant it is???

Anyhow for what it is worth (not much I suspect) see the attached

and I ended up having to do a "manual" installation.

The details of this process are given in this thread

https://www.mapleprimes.com/questions/229832-Phyysics-Updates-Installation

You will have to read quite a lot of the thread to get to the part which makes everything "work"

  1. It really ought to be "easier" to do this
  2. the 'help' pages for the 'events' option definiely could be clearer

BTW I admire Rouben's response - but iti took me a while to figure out how it was being done!

Anyhow, I get the same answers, in a less subtle (but more understandable?) way in the attached

No-one is going to actually run this code for debug purposes, since it usses numerous system calls to external software, and

  1. Users (such as me) may not have the required external software installed
  2. Security issue: I  generally don't run MAple code with from this site which contains system calls - one never knows what might happen to my OS!

This means that any debug which I do is just based on reading your code - not executing/debugging it. So here goes

#################################################################################################

The region of code in https://gricad-gitlab.univ-grenoble-alpes.fr/magronv/RealCertify/-/blob/master/multivsos/multivsos.mm which is causing the problem, is shown below. These are lines 256-272 approximately, where I have highlighted line 206 - the one referenced in your Error message Error, (in sos2sdp) invalid arguments for searchtext |multivsos/multivsos.mm:260

  fd := fopen("multivsos/out.dat-s",READ,TEXT):
  nl := "":  yMatText := "yMat := ":  
  while true do     
    nl := readline(fd):
    if SearchText("objValPrimal",nl) = 1 then objValPrimalText := StringTools[RegSubs]("objValPrimal = (.*)" = "\\1",nl): break: fi:
  od:
  while true do     
    nl := readline(fd):
    if SearchText("yMat",nl) = 1 then break: fi:
  od:
  while true do
    nl := readline(fd):
    if SearchText("main loop",nl) > 0 then break: fi:
    yMatText := cat(yMatText,nl):
  od:
  fclose(fd):
 yMatText := StringTools[SubstituteAll](yMatText, "{", "["): yMatText := StringTools[SubstituteAll](yMatText, "}", "]"): yMatText := StringTools[SubstituteAll](yMatText, "][", "],["):

Just from reading the above code is seems odd that some of the commands from the StringTools package, eg

StringTools[SubstituteAll], StringTools[RegSubs]

are given in long form, ie prepended with the package name. On the other hand the case-sensitive 'search' command, ie SearchText(), is not prepended with the package name.

I can find no evidence that the StringTools package has been loaded elsewhere in the original worksheet - so I'd be tempted to replace all occurrences of 'SearchText()' in the above section of code with 'StringTools[SearchgText]()'  just to see if itt makes any difference.
