Please how  can I use getdata to extract only 200x2 of 208x2 matrix from maple to excel.

For instance I have:

Q:= ( seq( seq( plottools:-getdata(ans1[s1,3])[j,3],j=1..3), s1=1));

It returns  208x2,  200x2 200x2 matrices and I can't extract it using 

`<|>`( seq( seq( plottools:-getdata(ans1[s1,3])[j,3],j=1..3), s1=1));

because the matrices have different dimension. Please, how can make 208x2 matrix to 200x2?

After I refer to the Mersenne prime number table, I found the following result
5, 31, the number of digits is too large to be determined
13, 8191
17, 131071
19, 524287
If the following elements all yield composite numbers
So:
2, 3, 7, 127
The length of the sequence with only 2 only generators reaches 4.
Due to its particularity, it is guessed whether 2^(2^127-1)-1 is also a prime number,
and whether the sequence with 2 as the generator is an infinite sequence of prime numbers Woolen cloth? 
Then perfect numbers are also infinite.

I have created some plots of inverse primes  like this example1.pdf .

The filled color-shape in the middle is what I want do do with all areas in this picture or in other pictures.

In other words the goal is to fill the differnt areas in the print with different colors.

So I need to find the points of the Polygons, as I have done by hand with that yellow Polygon.

A procdure that is ready will give give the crosspoints of the lines.

These are the line-coordinates (the 1st number ist the number of iterations)

2*L[1]=number of lines in L

L:=[14, [[1, 1], [1, 26]], [[1, 26], [26, 26]], [[26, 26], [26, 37]], [[26, 37], [37, 37]], [[37, 37], [37, 39]], [[37, 39], [39, 39]], [[39, 39], [39, 20]], [[39, 20], [20, 20]], [[20, 20], [20, 23]], [[20, 23], [23, 23]], [[23, 23], [23, 30]], [[23, 30], [30, 30]], [[30, 30], [30, 70]], [[30, 70], [70, 70]], [[70, 70], [70, 45]], [[70, 45], [45, 45]], [[45, 45], [45, 34]], [[45, 34], [34, 34]], [[34, 34], [34, 32]], [[34, 32], [32, 32]], [[32, 32], [32, 51]], [[32, 51], [51, 51]], [[51, 51], [51, 48]], [[51, 48], [48, 48]], [[48, 48], [48, 41]], [[48, 41], [41, 41]], [[41, 41], [41, 1]], [[41, 1], [1, 1]]]

These are the crosspoints:

cp := [[23, 26], [30, 37], [32, 37], [26, 30], [48, 45], [39, 34], [41, 34], [45, 41]]

To plot the pdf I used this code:

poly2 := [[32, 32], [34, 32], [34, 34], [39, 34], [39, 39], [37, 39], [37, 37], [32, 37]]

poly 2 is just an axample, how it looks like when its ready.

display(seq(line(op(L[i])), i = 2 .. 2*L[1] + 1), polygonplot([poly2], color = "Resene GoldenTainoi", axes = none, style = polygon), color = blue, thickness = 0.8);

So I hope, you can help me :)

This is a beautyfull way to paint a prime  by just printing the remainders of the recursive dividing of the inverse prime in lines.

Thanks a lot,

For example my friend emailed me.

His email address is oneman@gmail.com, the email content is HELLO.

How does Maple print HELLO to the screen so I can see it?

Thanks for your help!

I make new cone puzzle. However, I cat't make function l(θ). Can maple solve this puzzle?

θ=90 degree is a YouTube problem I found. 

Good day.

Several years ago, I obtained access to a clustering package that was useful to my studies using Maple 17.

In the meantime, I switched to another computer and now, I  cannot access the file, ClusterAnalysis.mla.

Unfortunately, I do not recall how I was able to access this library file.

Can anybody please advise me on the exact steps that are necessary to initialize and execute this file?

Thanks for reading ...

Please help me create a variation table of the function in maple like the above figure.

I haven't managed to round values with units, and get the trailing zeroes cut away, so I'd like to use the MapleTA:-Builtin:-numfmt function to do the job.

The problem is, that this function doesn't accept values with units.

I have managed to write a rounding function to do the rounding, but the problem here is that it will write the values with trailing zeroes, which isn't what I want.

Any ideas how to fix that?

I want to change the colors of a contour such that the region above zero is represented by a different color instead of yellow color,  and that the colors for conts <0 are one set of colors (maybe yellow to red), and the area for which conts >0 is one color which is very different from the others (so maybe white).

I want to check whether the last expression is zero symbolically in maple. I am trying to learn how to calculate symbolically in Maple. Any suggestion would be very appreciated.

Hi senior, I am using Maple 2022 version. I am facing a issue regrading opening of maple worksheet. If connected with wifi then maple worksheet will open and work properly, while i disconnected the internet, maple crashed and pop up a message to activate license again..

Using plot3d(..., style=surfacecontour, ...) or contourplot3d(...) displays wrong level curves when some axis are switched to a log mode.

Example:

The problem is not dramatic because there is a workaround.

Hello,

    I am regularly using tabled data for things like material properties, or other tabled look-up data from induustry or custom datasets.

    I have not used workbooks within Maple and yet see that exel files or other data sets can be "connected(?)" in the workbook tree.  Is this helpful?

    What is the best practice view of connecting to DB data and looking up variables that repeat project to project or worksheet to worksheet - without pulling into memory the full datasets for each ref call?

All thoughts appreciated.   

P.S., Tables vs. dataframes are a slight confusing matter also.  The access to the cell info seems different based on dataframe/table/matrix type.  I have no problems with matrix element access.

Thanks,
Bill

when i try to save my program maple is close, crashing. how can i fix this?

Hello every one, i am New using maple and I am trying to translate This code from matemática to maple, someone can help me please?
