I would see on the monitor the vector n > 10 with all his components, but the output of Maple is always the structure of the vectors.

For example, if I write:

There is a cool option of dropping one graph from multigraph (after that it goes as separated one). How to get  this dropped structure itself? I.e. i have "graph" component with command AllPlots that itself is

AllPlots:=plots[display](AllPlotsStructure,...);

AllPlotsStructure is a list of plot/textplot.

After all i removed one structure by drag-and-drop on component. How to update AllPlotsStructure correctly?

I have a calculation (analytic) involving sums (finite) that ends up with an expression structured like a sum over an expression with several terms, like

sum(Y(t)*cos(omega*t) + a*sin(omega*t)+b*cos(omega*t),t);

(The real case is more involved but this simple example shows the issue.)

What I want is to distribute the sum over each term separately, observing that a & b are numbers & therefore can be pulled out of the sum. Note that the expression...

How would you transform a 3D plot structure into a 2D plot structure? I have in mind 1) creating a 3D plot with odeplot or with plot3d, 2) selecting (say) 4 orientations, 3) transforming each into a 2D plot, 4) exporting the 2D plots using the Standard GUI.

The reason behind my question is that the best-looking exported plots that I have been able to obtain with Maple are 2D plots exported as postscript with the Standard GUI. 3D plots don't look nearly as good when...

Hello,

I have some difficulties to create an X-Y chart and what data structure I should use.

I have a loop, I set the maximum number of iteration to nmax.

At the end of each iteration, I will retrieve two information (variables):

-iteration number, 1 by 1 until nmax, integer: n
-an value associated with this iteration, integer: v

I will store iteratively these values (at least v) at the end of each loop...

Here is the sort of data I want to plot:

plot([seq([i,i],i=1..10),seq([i,1/i],i=1..10)],style=point);

The above works (Maple 14, Windows 7, Standard GUI). but I'd like to use different scales on the left- and right-hand sides, e.g. raise the second plot by a factor of 10.

I thought dualaxisplot would be the ticket, but I haven't been able to make it to work. It may have to do with the fact that my data is a list of coordinates rather than a function ...

In the help, a structure block diagram is given under the DynamicSystems[SystemConnect] command for the explaination of the use for the general connection,

that's intuitive and gives clear connections among every structure block,

so, I wonder whether there is a method to build that diagram or similar fig using the GraphTheory package,

that will be amazing,

is there a method? I want to know how to get it.

Hi there. I have two expressions of type Matrix(7x1), one I entered directly and the other one is the result of a  procedure calling. They only differ by the term [1,1], so when I do a comparation of the appropiate submatrix using Equal I get a positive answer:

>Equal(SubMatrix(atataaV(1,1,1,1,u1),2..-1,1),SubMatrix(u1,2..-1,1));

true

Now, the elements of the submatrices depend on the symbol 'n',...

I have the following script 

Download display_plot_-plot_s.mw

, where i tried to import two collumns of data from excel, what am i suppose to put after "display" to obtain the plot?

Is it possible to import the branch structure of discussions from the old MaplePrimes?  In many cases it looks like all the replies are put into a flat list.

Is Maple able to recognize Excel sheets, or maybe other data structures to which I can export Excel tables and have them represented as Arrays or tables or anything else in Maple?

Our first article introduced Maple's polynomial data structure and explained how Maple spends a lot of time working with monomials. To multiply polynomials having n and m terms, Maple must construct, simplify, hash, and sort all nm pairwise products to determine what monomials are equal. This work is performed even if the result has far fewer than nm terms, making it a rather inefficient way to multiply large multivariate polynomials. This article describes a new data structure for multivariate polynomials that is being added to Maple for a future release.

This is the first in a series of short informal articles about our efforts to speed up polynomial arithmetic in Maple. We begin with an example of how polynomials are represented in Maple right now.

When you enter a polynomial in Maple, it creates a generic data structure like the one above. In Maple's representation this polynomial is a sum of terms that is 11 words of memory long where each word is either 32 or 64 bits. For each term it stores a pointer to a monomial followed by a coefficient.

When working with large sparse linear systems you often want to look at their non-zero structure, however Maple's existing tools are all designed for dense matrices. I wrote a little tool to produce images like this in reasonable time. You can download the code here, and the rest of this post is a quick tutorial on how to use the included command. Maple 11 is required.
