Hi,

I've just got interested in MapleFlow (and downloaded the trial). I looked at the previous post but I have seen very little activity for MapleFlow. Is it still alive?

Best regards,

Hi,
I'm trying some number theory functions and got a problem with prime factorization.

When I try the function ifactor in Maple, it works perfectly, but when I try it in MapleFlow, I get:

ifactor(50) = 50

Is there something I'm missing?

Thanks in advance for any help.

Low power user (occasional) here! I would like to extract the parameters from a curve fit and assign to another variable?

Hi,

I just got 2 questions regarding symbols and answers in MapleFlow (I might be doing something wrong here).

- In trying to input the integral int(F(x), x = -pi/5 .. pi/5) - this is just an example! - as a symbol,

MapleFlow doesn´t accept fractions or multiplications for bondaries values, unless I input "int(F(x), x = -pi/5 .. pi/5 =". Is there anyway to do it?

- is it possible to have the answer as , like in Maple, instead of ()symbolic expression) or 1.18 (numeric expression)?

Thanks in advance for your help.

The complete Maple Conference 2024 program is now available online. You can view it HERE.
Thank you to all those who voted for the "Audience Choice" sessions. The winning topics are listed in the program.

Registration is still open and free of charge.  

We hope to see you there!

I am stuck this command works seemlessly in Maple:

ThermophysicalData:-CoolProp:-Property(D, T = 20*Unit('degC'), P = 760*Unit('mmHg'), water)

but it does not work in Maple Flow. Does anyone knows why? Thank you so much for your help in the matter.

We've just launched Maple Flow 2024!

You're in the driving seat with Maple Flow - each new feature has a straight-line connection to a user-driven demand to work faster and more efficiently.

Head on over here for a rundown of everything that's new, but I thought I'd share my personal highlights here.

If your result contains a large vector or matrix, you can now scroll to see more data. You can also change the size of the matrix to view more or fewer rows and columns.

You can resize rows and columns if they're too large or small, and selectively enable row and column headers.

If the vector or matrix in your result contains a unit, you can now rescale units with the Context Panel (for the entire matrix) or inline (for individual entries).

A few releases ago, we introduced the Variables palette to help you keep track of all the user-defined parameters at point of the grid cursor.

You can now insert variables into the worksheet from the Variables palette. Just double-click on the appropriate name.

Maple Flow already features command completion - just type the first few letters of a command, and a list of potential completions appears. Just pick the completion you need with a quick tap of the Tab key.

We've supercharged this feature to give potential arguments for many popular functions. Type a function name followed by an opening bracket, and a list appears.

In case you've missed it, the argument completion list also features (when they make sense) user-defined variables.

You can now link to different parts of the same worksheet. This can be used to create a table of contents that lets you jump to different parts of larger worksheets.

This page lists everything that's new in the current release, and all the prior releases. You might notice that we have three releases a year, each featuring many user-requested items. Let me know what you want to see next - you might not have to wait that long!

I learnt that MapleFlow (MF) was a product similar (and better) than MathCad (MC). I have a old copy of MC, v.11 (with Maple symbolic engine) and I compared it with MF from my engineering dep. 

Can one kindly explain why Sum of a simple Matrix does not work, if the index is placed as exponent? Here what I did:

Hi,

just a simple question: Is it possible to write procedures in Mapleflow, like (this is just a simple example, not what I would like to code!):

add4:=proc(a,b,c,d) a+b+c+d end proc

and, if so, how to do it? I've tried the above code but got the error

"expecting operator"

I am new to Maple Flow and am constantly having issues like the one shown below. A cell will become corrupted somehow, and the kernel will crash or freeze. I can save and quit, but if I re-open the file, the crash will happen again before I can diable evaluation. My questions:

1. Has anyone else had this issue? Was it solvable?
2. Can evaluation be disabled by default? Its possible in Maple but I don't see how in Flow.
3. Can the kernel be restarted and reconnected (like Jupyter Lab)?

I cant expand the cell in question because of the crash, but this cell isn't the issue. This is happening all the time.

Thanks in advance

When I annotate a MapleFlow worksheet, I would like to typset some text as a superscript or a subscript for clarity, and to match the math expression. Is there a method to format text using superscripts and subscripts?

Maple Transactions frequently gets submissions that contain Maple code.  The papers (or videos, or Maple documents, or Jupyter notebooks) that we get are, if the author wants a refereed submission, sent to referees by a fairly usual academic process.  We look for well-written papers on topics of interest to the Maple community.

But we could use some help in reviewing code, for some of the submissions.  Usually the snippets are short, but sometimes the packages involved are more substantial.

If you would be interested in having your name on the list of potential code reviewers, please email me (or Paulina Chin, or Jürgen Gerhard) and we will gratefully add you.  You might not get called on immediately---it depends on what we have in the queue.

Thank you very much, in advance, for sharing your expertise.

In MapleFlow lowerscript L is not easily available.  It should be accessible with the CRTL+space after typing L.

Or in a list of common symbols (that pallete is not available in Maple Flow)

I had to to use maple to discover how to enter it.

`ℓ produced the correct result and then deleting the quote I could achieve the desired result.
