I am solving a dynamic problem however due to the complexity of the problem, the software runs out of memory. To avoid the memory los i am tring to write each time step solution into a text file however in order to do that i need to open a file using "fopen"

unfortunately this command enables writing to a file only if followed by "fclose" yet if the program stack before the file is closed the data is lost. on the other hand if i close the file after every time step the new file overrides the old one

I had a look at the Maple application "An Interactive Stock Quote Importer"  www.maplesoft.com/applications/view.aspx

which is quite nice :-)  I did not really understand how the author (Samir Khan Maplesoft ) managed to download

yahoo finance data directly inside Maple so I sent him an email asking. He sent me some quite nice code (which I

simply put in a procedure ) that downloads data for any specified ticker symbol from yahoo finance:

Hallo!

I have converted a decimal number to hexadecimal, the result in hex is: 18DBD3547552C73BE4DE87731C500.

I think the from Maple converted (decimal to hexadecimal) number ist Big-Endian.

Is there a command in Maple to make this number 16 Byte long (00018DBD3547552C73BE4DE87731C500) and to convert this hex-number to Little-Endian (00C53177E84DBE732C554735BD8D0100)?

Thank's for help.

Is it possible to see the algorithm used by msolve(eqs,2) ? The help page just says

"The procedure msolve has special code for efficiently handling large systems of equations mod 2. "

but I would like to know exactly what it is doing.

I tried print(msolve); and then print(ModularSolver:-Solve); but didn't get anywhere.

How can i plot x-exp(-y^2)=o and sin(5x)/x + 2 − (y − 1)2 = 0.on the same graph maple just repeats whatever input i put in

Is it possible to change the numbers on the dials and gauges to read say $5 $10 etc... or  10% 20% ...?

How about embedding a label directly on the dial?  Like having the actual name of the dial appear within the graphic. 

I want to add some conversion units to the units calculator in Assistants.  Can I do that? 

Specifically I want to add fuel conversions in the assistant.  mpg, L/100km, km/L  etc ...  

Good Afternoon Everyone,

Would any body be kind to see why Maple would not replace the following in the attached differential equation.

Regards,

Moses

I would like to plot the real and imaginary parts of a single complex function, not two different ones.  I understand that choosing the option of "expression_plot" will allow this.  Doing this continues to yield an error.  I would like to see the precise formatting of this command.

  Thank you.

Hello.

I am relatively new to MAPLE. I have a large fraction (actually a Bessel differential equation) which I like to break into single terms, i.e. to cancel the denominator with single summands.

"(diff(g(r),r)*f(phi)*r+r^2*diff(diff(g(r),r),r)*f(phi)+g(r)*diff(diff(f(phi),phi),phi)+h^2*g(r)*f(phi)*r^2)/g(r)/f(phi) = 0"

I tried full partial fraction, but it doesn't accept "g(r)*f(phi)" as variable.

any ideas?

all the best.
 

Hi all, i have been using maple for some time now. But one thing still bothers me. The use of radian in stead og degree. I found a way to work around it, but still.

So i looked at the help file, and found some intresting commands like:

• AddSystem - "The AddSystem(unit_name, opts, units) function adds or redefines a system of units in the current session"
• UseSystem

Can't that be used to forcing maple to calculate in degrees rather then radian.

hi!

i am new to Maple (just purchased 13) as well as trigonometry, which i am using Maple for! i'm trying to use Maple for all of my Chem and Trig homework because I am a Physics major and I think i'll probably be using this for years, so might as well get accustomed now!

basically, one of the problems has a figure with a unit circle on a cartesian plane. the "t-line" (or plot line, i dont know) has tick marks that represent the length of (t), and they go from 1 to 6. to give a better "mental image":

hi all! i am **brand new** with maple 13 as well as trigonometry, which i am using the program for. i have figured out how to plot the unit circle with the command:
