Hi I have just begun to use Maple and there are some function I am not able to use.I have 3 questions

1. I would like to plot the normal function (given a specific expected value and variance): is there a simple function to do it or I just have to re-write the function inside Maple?
2. is it possible to draw a line for a specific value of the graph, let's say x=1 without drawing an entire line for the graph (just to highlight the point)
3. is it possible...

The surface in above image is a portion of the graph of
some mathematical equation.

Let's do some brainstorming:
Can you guess what's inside the surface?

Hello, MaplePrimes!

Could you please tell me, how to select which variables are “input” and which ones are “output” during a custom component definition in MapleSim?

Thank you.

Hi,

Currently I have to deal with this nonlinear differential equations. The "Newton iteration is not converging" is the main problem. Could anyone propose some solutions?

Thanks a lot.

Hello,

I use the following commands to generate the frequency response of a system,

with(DynamicSystems):

sys := TransferFunction(10/(s*(s+1)*((1/4)*s^2+1))):

NyquistPlot(sys)

but the figure which maple outputs seems not good because the ranges of x-y axises are very large. I try to use NyquistPlot(sys,view=[-20..20,-20..20...

Hey Mapleprimes,

 I have a set of 3x4 Matrices and i need to filter some out, but cant find the right maple commands. Example Matrix:

[2 4 0]    row 1

[0 2 2]    row 2

[0 2 2]    row 3

[4 4 4]

row 2 = row 3

1. If all elements of a matrix have a common divider, such as 2 in the example matrix, I need to store the simplified matrix, meaning the one with all values divided by the common divider....

I am setting up a new machine.

I was running Maple 13 on another machine running Fedora Linux 13.   I don't remember if I had any problems setting it up, but it was running fine.

But I removed it from the old machine and installed it on the new machine which is running Fedora 14 Linux.

Maple 13 loads but I get a message from SELInux about a problem with Maples's mserver and execcstack.   ...

I have problems with a variable that is given only implicitly. Maple provides incorrect answers but I am not sure where I make the mistake. Thanks for any comments! Here is what I do:

(1) I use "assume" to set properties of two paramters a and b.

> assume(a > 1);
> assume(b > 1);

(2) Since the variable "x" is given only implicitly, I define an implicit function following the description in the thread "How to define an implicit function in Maple?".

Hi, i want to overload the operators of union, intersection etc. But i do not know how to start this. kindly provide basic help. thanks.

Here is the info that i have i need to plot a piecewise-defined funtion that has a value sin(x) between -2*Pi and -1, value x-1 between -1 and 2, and a value of cos(x) for x between 2 and 5. Can anyone help me?

Hello,

After using the following command

print(plots:-display(%,%%)):

I generate a graphic. This graphic is possible to export as JPEG format using the mouse (selecting the option to "export").

Nevertheless, I would like to export (in JPEG format) this graphic (plot) using commands of Maple. How could I do that?

Thanks a lot for your attention,

Jean-Jacques

I am attempting to create an interactive number line.  I would like to allow the user plot a point on the number line with the mouse.  The value of the point plotted would be passed back to a Java program.  Can Maple do this? What is the best way to implement this?  

Thanks

Hi,

I'm a beginner in Maple and I struggle to plot the function under a number of constraints.

My function has 2 varying variables (lambda and m):

d:=(lambda, m) -> (0*lambda*m*1*0.2533*5.251234*(9)/2/((4*5.251234-1)^2)+ 1*((m*lambda*1*0.2533)/4 + (1*0.048236*(5.251234-1)*5.251234)/((4*5.251234-1)^2)))-(1*0.048236*0.2533*(0.2533-0.048236)*1*(1+m*lambda)/((4*0.2533-0.048236)^2)+ 0*lambda*m*1*0.2533*5.251234*((4*5.251234+5))/2/((4*5.251234-1)^2));

Hey there,

i have (for example) these two B/W images and would like to calculate the displacement of the cross via an image correlation.
does anyone has an idea how to succeed???
is the Correlation function in the Statistics package usable for this task?
thanks in advance!
