I am not being unreasonable, I am simply being a user.

I find it very confusing to mix ?name with general search, which seems what ? is doing.

If ?name is meant to be like wild card search, which picks any help page with "name" in it, then it should be something else, and not overload ?name on top of it.

You can have ??name for example, or new command, call it search(name), which will act as general wild search. But ?name should be reserved for only known system command and symbols. period.  ?foo should not bring up a help page on units of length. This makes no sense.

What does Mathematica do if you use lowercase pi?

it is as if one typed x and x was not defined.

The difference is that in maple, when I do ?pi  it does actually brings up an official help page on Pi. Which makes one thinks they are the same or they might not notice the upper vs. lower case.

In Mathematica, if I do  ?pi, it returns message saying symbol pi unknown.

 

If pi is just like any random symbol, then I would suggest that ?pi should return symbol not found in Maple. It is very confusing to bring up help pages on something that is not defined in Maple.  I even now tried  ?foo and Maple brought up a help page  titled "units of length" 

Amazing.

 

 

I do not have E:\ drive on my computer and do not have shootlib. and no Shoot package either.

 

@tomleslie 

thanks, that works. It was a syntax issue. I did not know the Maple syntax for this. I tried what you have, but used different syntax, which did not work for me:

solve({eq>0,0<x<1,0<y<1} , {x, y});

The syntax 0<x<1 woks in Mathematica, but now I know it does not work in Maple. One must write 0<x,x<1.

No problem. Thanks. (I find it simpler to 0<x<1 than 0<x and x<1. I wonder why Maple could not support this in the future. Might break old code?)

 

@Carl Love 

that answer does not explain why the author did not simply include the option subtype= Matrix to the rtable command.

How would doing the above changes things? Is it just more efficient to have done so when creating the rtable since one anticipate to convert it to Matrix?

 

@Alejandro Jakubi 

Yes, it is buggy, This is what it looks now in Browse()

Which is impossible to read. I use
interface(verboseproc=3);
print(dsolve);

which is much better. (but would have liked to have line numbers as well, but at least one can read it).

@acer 

What you see at the end of the AiryBiZeros procedure is an unevaluated return

Thanks. But now I am more confused. Then where is the actual code that evaluates this:

evalf(AiryBiZeros(10))
           -12.3864

All what I see in the listing is checking for arguments?

 

@Alejandro Jakubi 

e.g. AbelMap is actually a module under algcurves with 32 private procedures itself.

 

Well, the I will be going by what ShowContents(LibLocation); shows. I assume that only user visible commands are listed. For example for maple.mla, it lists 12,517 names/commands/symbols. Then I will need to figure a way to find if the name is symbol, or command/procedure or what it is.

you have coupled and nonlinear odes.  Why do you expect that there is a closed form solution?

@Carl Love 

The above method you described does not work for me. I am on windows, 18.02. And I just tried it. I kill mserver.exe from task manager. Then when I do file->new worksheet, it says

So I am not able to even creat a new worksheet. And I do not know how to create a new server other by closing Maple and starting it again.

 

The best solution is to define 0^0 as not defined.

In Mathematica it says:

0^0;
Power::indet: Indeterminate expression 0^0 encountered. >>

 

@ecterrab 

Yes, a mini-installer will be great. Thank you. If this was in the Linux world, one would just type

sudo apt-get update  maple-physics-package

:)

@Markiyan Hirnyk 

I do not understand. I am clearly asking for an automated way to obtain the Maple command that would have generated the plot after I edit it using the menu.

You never showed the way to do this. You simply showed the Maple command to do this one simple example.

What if I make many edits to the plot using the menu, and now I want to save the Maple command to generate the plot again. How would I obtain this command automatically? 

I thought the question was very clear.

@Markiyan Hirnyk 

This does not really answer my question at all.

@ecterrab 

thanks for the updates. Is it possible to also automate installation of the Physics package in similar way to updating Maple itself? Clicking on a button to check and do the update is much easier for users than manual updates which involves downloading zip file and dealing with directories and such. 

This will make it much easier to update the Physics package for many users.
