So I have a problem when copying multiple output from Maple to Word. I am using a simple example here. 

When I copy each part of the output as an image SEPERATELY, it comes out much cleaner than if I highlight everything together and then copy. Is there a reason this is the case and is there a way to fix this problem?

Here is the Maple Code:

with(plottools);
with(plots);
ttt1 := textplot([0, 1, "3  +  5  =  __", color = "black", font = ["Arial", "bold", 120]]);
display(ttt1, size = [1000, 200], axes = none);
ttt1 := textplot([0, 1, "1  +  3  =  __", color = "black", font = ["Arial", "bold", 120]]);
display(ttt1, size = [1000, 200], axes = none);

I also uploaded the Maple Worksheet

Here is the output:

There are TWO imges in the output in this example. I tried copying both together and pasting them, and then I tried copying them individually. The output is very different in quality.

The one copied alot is much cleaner once copied and pasted in Word. Does anyone why this is happening? I don't want to have to copy images individally for obvoius reasons. I know this example is only two images but what if there was alot more, etc.

Thank you

Hello,

    I am manually re-creating the TS diagram for phase plot of fluid=air for use in a report as a pretty plot.   The TemperatureEntropyChart function is colored in grayscale.  I really need to change to colorized for additional data being added.

   The code to generate the various isobars color gradient is shadebetween two curves.   

    Using the code method to plot leaves white gaps in the discontinutiy of the plot curves returned from the Property function at the liquid and vapor lines.   I have manually connected the horizontal "under the dome" in a matrix of X,Y for each of two isobar curves.

   However, the shadebetween doesn't seem to like the two X,Y matrices for the curves as inputs to shadebetween.

    So,...   Q:   1.)  Can the color be changed using the TempertureEntropyChart function,..or
                      2.)  Can matrices of unequal X,Y values (scatterplot type data sets) be used for the curves in shadebetween command?  The help infers the Y (v, of (u,v))  values need to match.

Thanks,
Bill

Hello guys
Could someone help me create a simple palette to contain, for example, three functions that I use constantly?

           conve1(a), conve2(a) and conve3(a).

I tried through the help documentation, but I couldn't.

Sincerely,
Oliveira

I have just installed the Google Maps package but when I run the commands I only get empty results and some errors

Any thoughts of what can be wrong. Have latest Montery OSX

Mathematica's Dimensions returns a list of the allowed levels, which has been implemented in Maple as . But 

MmaTranslator:-Mma:-Dimensions(<<1 | 2>, <1 | 0>>);

returns [6], and 

MmaTranslator:-Mma:-Dimensions([[1, 2], [1, 0]]);

returns [2, 2, 4]. What happened here?

It should be [2, 2].

restart;

MmaTranslator:-Mma:-Dimensions(linalg[matrix]([[1, 2], [1, 0]]));

[0]

(1)

MmaTranslator:-Mma:-Dimensions(< 1 , 2 ; 1 , 0 >);

[6]

(2)

MmaTranslator:-Mma:-Dimensions(convert(`{{1, 2}, {1, 0}}`, FromMma));

[2, 2, 4]

(3)

MmaTranslator:-FromMma(`Dimensions[{{1, 2}, {1, 0}}]`, evaluate);

[2, 2]

Hi Everyone,

I intend to find the invariants of a 2nd-order Tensor using the representation of the rotational group as an Infinitesimal generator. However, maple does not seem to find the correct invariants $\tr \mathbf{a}$, $\tr \mathbf{a}^2$, $\tr \mathbf{a}^3$. Maple only returns an empty set. I can't seem to figure out why that is the case.

Here is my code

Any input would be appreciated!

I just wrote up a bug report (aka "Software Change Request") but got a "We are currently experiencing technical difficulties" error so the report is not being sent.

I will just post here about the bug in case anyone knows what it is.

I am going through the Multivariate Calculus Study Guide. I went to section 1.1, and was going through the examples. At the end of an example is a link "Next Example", but when I click this I get an error and have to go back to section 1.1 Table of Contents. Kind of annoying. Also, I notice that Maple simply crashes seemingly randomly when going through this study guide. Very annoying.

Here is a screenshot of the write-up to the bug report service that isn't working, for the record

I was wondering if this is something wrong with my Maple installation or if other people experience it too.

I embed Maple code in Mobius for test questions. A simple 2-step CRR tree gives significantly different answer from the calculated by hand or by R's fOptions. Here is the piece of Mobius/Maple:

$ct = maple("
    with(Finance):
    S0:=50; X:=50; Ty:=6./12; r:=0.07; sig:=0.3156; n:=1;
    dt := Ty/n;
    u  := exp(sig*sqrt(dt));
    d  := 1/u;
    pu := (exp(r*dt) - d)/(u - d);
    pd := 1 - pu;
    BT := BinomialTree(Ty,n,S0,u,pu,d,pd);
    cT := ST -> max(ST - $X,0);
    Ec := EuropeanOption(cT, $Ty):
    LatticePrice(Ec,BT,$r);
    ");

The answer is: 6.545478168.  Exactly the same with BlackScholesBinomialTree

The correct answer should be 6.32

In this case the solution by hand is simply e^(-0.07*05)*0.5236*$12.50

R confirms 6.32:

CRRBinomialTreeOption(TypeFlag = "ce", S=S, X=X, Time=T, r=r, b=b, sigma=sig, n=n)@price

The error decreases with the increase of number of steps. All quantities before LatticePrice are calculated corectly. Any idea of what the reason might be?

Thanks.

Dear,

I would like to do equation of motion calculations using spin matrices.

I would like to do calculations using the  coupling.

Thanks for listening.

I'm trying to use Maple to take the following integral for positive values of a, b, c and non-negative integers i and j.

I know that for fixed values of j and k this doable — for example, for j=k=0 Mathematica gives

I'm trying the following code in Maple:

int(exp(-(x + y)/2)/(a*x + b*y + c), [x = 0 .. infinity, y = 0 .. infinity]) assuming (a::real, 0 < a, b::real, 0 < b, c::real, 0 < c)

Am I doing anything wrong?

Hi dears

I have a pde system and want to get the solution of this system step by step. is there any command or bunch of commands that could help me?

(pde = partial differential equations)

simplify(sqrt((x^2 + y^2)/x)/sqrt(x^2 + y^2)) assuming x>0, y>0

is not sqrt(1/x), why?

Warning, data could not be converted to float Matrix

Hi all, 

I am working with the physics package and I want to know if there is a difference between Physics:-CompactDisplay and PDEtools:-declare ?

As well as the difference between Physics:-Simplify and simplify.

For both cases, can they be used as the same ? Are they incompatible in some case?

Thanks !
