Hello

How does Maple create a graph from a 100000 elements vector (or a function that outputs that values)?

Does it plot some and reject others? plot all on top of each other? How can I change this behaviour?

How could I crate a graph where for every interval I see the max and min values, as in the trading "bar" charts?
(or any other idea to visualize that much info without needing to previously calculate intervals, mins and maxs myself)

How can I set  the boundary conditions? I need to specify diff(ui(e, t), e) and diff(ur(e,t),e) depending on e.  I write the rules:

> D1(e,t):=diff(ui(e,t),e);

 
> D12(e,t):=diff(ur(e,t),e);

 in order to use D1 and D12 in boundary conditions. 

I get error
> sol := pdsolve(sys, {D1(-500, t), D1(500, t) = 0, D12(-500, t) = 0, D12(500, t) = 0, ui(-500, t) = 0, ui(0, t) = 0, ui(500, t...

Hi, I have different parts of calculations, would be better if I use the function procedure.

May I know where I can find tutorials for it please? I have look through the user manual, but not many examples are given.

Thanks

Hi

Imagine I want to calculate this loop:

nn := nextprime(10^100); zz := 1;

for ii from 0 to 100000 do zz := mod(zz^2+1, nn) end do;

How can I avoid that Maple prints every iteration? I just want Maple to do it quietly, storing the value and get the last zz value  just by evaluating zz after the loop ends.

regards

"Welch-Satterthwaite formula":
With the package "ScientificErrorAnalysis" is easily calculated, the combined uncertainty of a mathematical model M = f (x1, x1, .. xn). But if I need to know the components of the calculation model uncertainty becomes very repetitive. For example to calculate the expanded uncertainty should be calculated uncertainty components model for using the Welch-Satterthwaite formula ". Which determines the effective degrees of freedom υeff:

Why does this not work?

restart:

P := Sample(RandomVariable(Normal(10, 10)), 500):
X := RandomVariable(EmpiricalDistribution(P)):

DensityPlot(X);

Hi

I would like to display mathematical expressions on a plot.

I am using the following command on the code edit region of Maple 15 worksheet, intending to show the maths on a plot.

t := plots:-textplot([x, y, typeset(a[0]=1)], align = above): #where x and y are the position

 plots[display]([p,t],labels=["X","Y"],font=["Times","Roman",20],labeldirections=[default,vertical],axis=[gridlines=10],caption=typeset(eta[12...

Hello all,

I would like to use Maple to simplify an expresion of this form:

I can define a discrete, finite universal set U, say the digits 1-5.

U:={1,2,3,4,5}

I can define a subset such as

X:={2,4}

Maple will compute the complement

U\X

but I cannot find any common textbook way of naming that complement that Maple will accept.  I cannot use a superscript c.  I cannot use a prime.  I cannot use an apostrophe.  I cannot use an overbar. Yes, I can type any of those using the various symbol...

Consider the differential equation $y^{\prime}=y-2$ with initial condition $y\left(0\right)=1$.

a) Use Euler's method with 4 steps of size 0.2 to estimate $y\left(0.8\right)$

I know how to do this by hand; however, I have maple 12 installed and was trying to figure out how to do this with Maple, and then make a graph showing each step of the function. Any suggestions. I have tried looking on mapleprimes, but it keeps pointing me to functions for newer versions of maplesoft, which I don't have....

I just started with maple 16 trying to complete an into assinment.  I am in a worksheet trying to just enter simple expresions 3+4 or 3*4 ect.  Whne i enter the operator + * using the keyboard, ther operators menu or pasting from notepad about 90%  of the time the previous number i typed disapears and the worksheet will no longer accept imput

I have tried reinstalling several times with no AV active even installed in safe mode same issue..

Hello,

I've written a code that I'd ultimately like to process in parallel over a grid of parameters, but before I can even think of doing that, I need to find a workaround for the memory allocation issues I'm having. Probably due to the way that it's written, Maple's built in garbage collection isn't working very well (if at all), and the code allocates another 100 MB or so every 10,000 iterations. Even if I content myself with running it for say 200,000 iterations,...

Hi, I have created over time a module with a number of procedures that are useful for me for certain calculations.

From time to time I am adding new stuff to it. Now I find that the thing has gotten long enough that (a) I need to do a lot of scrolling and (b) I forget where exactly certain procedures are in the file.

So I was trying to put in bookmarks that e.g. could carry the names of procedures, or sections of the whole thing. But Maple refuses to put more...

hi friends am trying code for 1d heat equation but my code is not giving me result which i needed...although its running but still am in doubt its not picking boundary conditions and initial condition in last loop of discritzed equation due to which my result are totally wrong.. am attaching worksheet please let me know where am wrong...will_see.mw
