Hi,

I wonder how it is possible to copy a text from Maple (version 11) to another application. I can highlight the text in Maple and press ctrl+c. But for example in word the only thing I get by pressing ctrl+v is an image of the text :(

I tried scan the image with an OCR but I assume that the resolution is too bad...there are tons of recognition mistakes..

Please give me advice :)

Hi folks. I have several applications that require multivariate (usually three variable) polynomials of degree at most n in order to fit data. Is there an easy way to generate these? I have in the past just written them out, but it seems inelegant, and one could easily mistakenly leave out a term when constructing a trivariate poly of degree 7, for instance.

Thanks in advance,

Hi,

I was reading the manual for Maple 13 and playing with some commands.

There is an equation: sin(x)=cos(x) and you can solve it by the solve command.

If you want all solutions, you just put there AllSolutions attribute and you get

(1/4)*Pi+Pi*_Z1~

I wonder why there is a tilde (~) behind "_Z1", because each integer satisfies

the equation (there is no need for an assumption).

Given the initial shape of the longitudinal axis of a curved bar is given by
y₀(x) = a*sin(Pi*x/L)

where a is a constant and L is the length of the bar

and proceeding to calculate the deflections due to deformation from the diff. eq.

EI (dy₁/dx) = -P(y₀+y₁)

the ode for deflections is obtained

dy₁/dx + k*y₁ = -k*a* sin(Pi*x/L)

where k is a constant = sqrt (P/EI)

Can anyone known of or recommend a program fro converting Mathematica notebooks or files etc., into Maple worksheets

Hi, Can anybody explain why Maple is crashing? Does it happen with Maple 13? > c:=alpha->solve(-alpha*(alpha+1)+x^(2/alpha),x); # I am too lazy to solve the eq by hand. > c(a); # Maple returns the correct value although that is difficult to see from the text version of the output /1 / 2 \ \ exp|- ln\a + a/ a| \2 / > c(1.5); # This always crashes Maple 12 on my Mac OS 10.5. Maple announces tha the connection to the kernel has been lost and I must restart. thanks,

If I have autosave on and I'm working on a worksheet and then if I change the name of the directory in the middle of my worksheet.  Autosave re-generates the old file name and saves it there.  Not really a major bug - not many people change the names of their directories in the middle of working on a worksheet anyways.  Never-the-less I managed to stumble across it. 

Try following,

Factor(a^4 + a^2*b^2 + b^4 + a^2*b*c + a*b^2*c + a^2*c^2 + a*b*c^2 + 
    b^2*c^2 + c^4) mod 2;

I couldn't get an answer in a reasonable time and interrupted calculations.

Hello,

I am maintaining a C++ application that requires Maple code generation features to produce C code.

This application uses the EvalMapleStatement (kv, statement) function, where 'statement' is actually a CodeGeneration[C](...); command.

The application has worked correctly before, and the generated code has been incorporated as modules into other applications that make use of it.

What do you think of the -1^n with no parentheses?

I'm guessing that the following behavior is a mapleprimes feature.

In the forums, when a thread loads, the display always jumps to the bottom of the page to an insertion point waiting in the reply box.

I like to read messages, before I reply.

Is there a way to turn off this "feature" ?

Cheers,

  ~ Mark

I just searched the mapleprimes site for information on how to mark all forum messages as "read".

In July 2005, somebody asked how to do this.  William Spaetzel responded by noting that there is no such feature and that he would think about adding it.  He repeated this statement, about two months later.

In March 2006, somebody else asked how.  There's no mapleprimes response to that message.

In July 2009, I'm asking again.

Has the suggestion from three years ago been officially rejected by mapleprimes?

Hi,

In which language the combinat package is written ? In C/C++ or in the Maple programming language ? When I call a combinat package function, from which file comes the function code ? I suppose the code is in a binary format, isn't it ? Thanks.
