I use Maple 13. The exported image file, for example .eps, is much smaller than V12. and the resolution is very low. How to change the resolution of the graphics? I find no way to change the DPI.

thanks

Hello everyone, here's an expression that I am working on. .014*(Int(r^2*Li[3/2](-exp(x-a(r)))), r = 0 .. 2)) which should be equal to a positive number say 1, where a(r) is a always negative and x can be any real number (positive or negative). I am writing Li[3/2](-exp(x-a(r))) equal to polylog(3/2,-exp(x-a(r)). Whatever values I plug in for x and a(r), the left hand side of my equation is always negative. But it should be a positive number. Would someone mind helping me out with this. Jeremy

Hi people,

I am kind of a beginner in using maple and need to make an animation of a little circle or a little square moving over a curve which is given. I have "the maple book" but it doesn't seem to explain anything like this. I have searched the internet but didn't find what i need. I really have nog idea how to fix this. I hope someone can help me out.

btw the whole problem is 2D so the curve is a function with only one variable

Thx in advance,

When I enter the followings commands with Maple 13, I get a result which I cannot understand.

 

restart;
with(RootFinding):
NextZero(t->cos(t), 0);
NextZero(t->diff(sin(t), t), 0);

I expect to get an approximation to Pi/2 in both cases. Why does computing the derivative in the procedure argument change anything?

 

I have a set of data and I have tried to create a line of best fit of the function a(1-exp(b*x)) xx := [180, 120, 30, 340, 215, 285, 175, 36, 420, 77]; yy := [10724.5, 6163.1, 2509.1, 26308.8, 5669.8, 19183.5, 23020.2, 2570, 16199.4, 9013.2]; I tried to use the "nonlinearfit" function but so far it comes up with an equation which does not fit into the scatter graph which I have also created with the data. Is there any other way to do this? Thanks

How can I solve a system like:
A^2=A

det(A)=3

det(A+B)=7
 

where B is a given, say 3x3 matrix and A is an unknown 3x3 matrix?

Hi, all, I know it can work over field, but I am not sure whether the groebner basis can be computed over ring in maple. Also i know singular can do the work.

I already asked this, but I still am not sure how to perform it, so here I'm again :-). I already read http://www.maplesoft.com/support/help/view.aspx?path=Define_external

Say I've got that mat_mult-Funktion like in the example in that link written down in a file called "code.c".

What now? Do I have to compile it? (Do I really need a .dll?)

Thx in advance for your patience!

Hi:

In some application I end up with maple-generated expressions that cover several pages. Things would be much simpler if I could define abreviations for lengthy expressions and express all subsequent results with their help. Some of that can be accomplished by alias and algsubs but not all of it. Anyone has any suggestions?

I'm trying to plot multiple feasible reagions of an linear program (which are defined by H] and H2, see below) into a single (!) plot using plots[inequal] as follows:

It is a naive question,but i can't find a way to make the axes of a plot bolder (I use Maple 12)..

Is there a way to do it??

thanx a lot!

 

 

Hi,

I'm new here and was wondering if anyone could offer me some advice on some work I'm doing.  I've written some code in Maple to generate images of fundamental domains in Hyperbolic 3-space, but in order to get the necessary results, I have to do some convex hull calculations.  Currently I'm using qHull for this, which works well, but outputs its results in the form of a text file, reading in the following format:

I have a series of points on the plane. I want to find an analytical function, which describes the curve drawn from these points. How can I do that?

Hi,

My equation is  Y= m.Y^3 + n. B

y: (-1..1) and  B: (-60..60)   have this values.

How can I fit the m and n parameters by using maple7?

And also how can I plot  Y(B) ? Thanks.

how is it possible to identify the independent variable that maximize(or minimize) a function?
is it important to know the kind of the function?

Is it possible to specify the independent variable that maximize a function just via it's plot?
