Can someone please let me know if there's a command which shows the name of the current (and running) worksheet? I would like it to be exported to an output file which is the easy part but I don't know how to automatically read it. Thank you very much.

Hello,
I have some variables which usually have a specific value. I also have some parameters which are calculated using the previously mentioned constants. Sometimes though I want to change the value of the constants and re-calculate the parameters. Therefore I created a library with the initial values of the constants which I load inside a procedure which calculates the parameters. That way I can change the value of the constants and the initial values are not overwritten. My problem is that I want to export the calculated parameters and the value of the constants at the specific calculation. How do I do that_ I don't have an array, table or anything like that. Should I put my parameters in a table?

Thank you for your time.

Hi there

I've got an 18*18 matrix which almost all of its elements are in parametric form. I Need to export this matrix to MATLAB to do some numerical alnalysis on that But when I click on  " export as MATLAB", the following error appears:

"can not convert matrix elements to float[8] datatype"

I wonder if thre's a solution to that or anyother way to move the matrix(as it is) to MATLAB.

I'll be appreciated your help

Does anyone have JavaViewLib running on Maple 18?  Could you help me out?  I can't get it running and I really need a way to export some 3d plots to a web page where a colleague can view them (rotate and such).

Thanks, Chad.

When I try to export my data from a spreadsheet to Excel, instead of numbers I get a long text containing numbers. For example instead of having just "11625.7677908435" I get "Typesetting:-mprintslash([11625.7677908435], [HFloat(11625.767790843516)])". 

Hi experts,

the standard resolution for maple contourplots is 72 dpi wich is not suitable for publication purposes. I need at least a resolution between 500 - 1000 dpi. How do I get better resolutions for my contourplots when exporting them to .bmp or .jpg-files?
Somebody any ideas?

i am trying to export an animated gif file but the export windows freezes and exports an empty file with zero bytes

the animation was created by: display(map(p, convert(A(() .. (), 2), list)), insequence = true)

i have tried to give maple some time (2-3 hours) and i even tried to restart the computer and lauch maple and try to export it but it didnt worked

how can i export it or how can i plot the using commands

 

When greek symbols are used in code edit region (by copying from worksheet 2d math mode), they used to get exported properly to PDF but the only issue was large code edit region used to get cut off. But now with this new 18.01 update, code edit region is not cut off but greek symbol inside code edit region are not appearing in PDF export instead just pink boxes. Has anyone else also encountered this issue and suggest a resolution.

I am making something for my math prof as a token of appreciation. It is a spiral slide rule designed to fit in a watch face, but it can be made bigger. I threw together a program to show what I mean:

https://www.khanacademy.org/cs/spiral-slide-rule/5831476045152256

I was told that maple can be used to create things like this, but since I am new to the software, I really don't know how to put something like this together. The best I could do was to make a spiral in polar coordinates, and plot my lists of points on top of it. However, this does not annotate the points and I can't make nice looking lines (the only point options in polarplot are stars, crosses, and other things that aren't what Im looking for).

Does anyone know how I could model this, and then export it as a format where I might be able to send to a printer to get it printed on specialty paper?

Thank you very much

 

EDIT: I uploaded my plot here, in case you want to see it:

Hi all,

I ploted the cylinder like this:

with(plottools);
with(plots);
display(cylinder([1, 1, 1], 1, 3), orientation = [45, 70], scaling = constrained, grid = [2, 2, 2]);

 

Is it possible to export nodal points of the plot?

Thank a lot.

Dear Mapleprimes,

I have been struggling with a problem in the last couple of days. I wish to export a Maple plot to LaTeX while ensuring font consistency. While searching for solutions online, I found the psfrag package in LaTeX. So far, however, I have been unsuccesful in making this work. As as test, I attempted to export plot(x^2) to LaTeX. I used the following code to convert to .eps which worked fine:

plotsetup(ps, plotoutput = `plot1.eps`, plotoptions = `portrait, noborder,height=5in,width=5in`);plot(x^2);

Then in LaTeX, I have:

\documentclass{article}

\usepackage{graphicx}

\usepackage{psfrag}

\begin{document}

\begin{figure}[!h]
\centering
\psfrag{x}{$ \alpha $}
\includegraphics[scale=0.5]{plot1.eps}
\end{figure}
\end{document}

However, no replacements are made. After intense Google searching I found the following post http://www.mapleprimes.com/posts/43255-Trouble-Replacing-Maple-Axes-Labels which to sum up argues that this was only possible with earlier versions of Maple.

Does anyone know if the problem has been resolved?

Does anyone know any other ways to ensure font consistency for plots imported from Maple to LaTeX?

Thank you very much in advance!

C

In ode solve command i generated a large array data. The output shows a large order matrix of this form

 

[110001x6 Matrix

Datatype:Anything

Storage:rectangular

order:Fortran_order].

 

I want to export this matrix into a notepad. Which can then be used for plotting in TecPlot. 

 

Looking for good response

 

 

I have defined the following procedure, S(x,a,b,s), in Maple with the goal of creating an exportable two column, multi-row array, containing the least positive real root of a high order polynomial f(x,y)=0 in the 2nd column, and a parameter y in the first column.

The procedure takes four numerical arguments (x,a,b,s) and varies parameter y from the initial non-negative value of a, by stepsize s, until the value min(b,1) is reached.

Unfortunately, the output 4x2 array only has the last calculated [y,solution] entries in the first row. Successive rows are filled with zeros.

Is there anyone kind enough to point out the error in the way I have defined this procedure? Many thanks in advance. Procedure is:

S := proc (x, a, b, s
   global Ry;
   for y from a by s to b while y < 1
     do R := Array(1 .. ceil((min(b, 1)-a)/s), 1 .. 2, [[y, FindMinimalElement(select(type, [fsolve(f(x) = 0)], positive))]])
     end do;
     end proc;

I have 2 problem with my jacobian matrix:

first: i can not evaluate 11*11 jacobian matrix. at last i can evaluate 10*10 matrix. can i solve this?
second: i want to export my matrix for matlab but i see this error : {export matrix"cannot convert matrix element to float[8] data type"}
so how i can use this matrix in my matlab code?
 my jacobian matrix:

Does anyone exports Maple worksheets to as a LaTeX file?

All my work is typed in LaTeX but I rarely export a Maple file as LaTeX because Maple uses its own LaTeX macros that in a generous evaluation are a lot of "junk" around the LaTeX code. In practice  it is is easier to copy and past the Maple output and then make modifications to LaTeX by hand than to modify Maple's LaTeX code.

Does anyone know of a more efficient alternative than manually copying and pasting?

The ability to export LaTeX useful LaTeX code should be a basic to any symbolic math software, this is one of the few feature os Maple that are really disappointing.
