Hey, I'm sitting with an extremely annoying problem. Basically, I want a "Mathematical Expression" component to include a definition of a variable, so I want it to say, for example, "h := 3", now, I can easily type this into the component field myself, and it all works great, but I want to manipulate the field with a button component. Every time I attempt it, it seems as if the ":=" symbol is protected, however I can write it myself without trouble.

From the help page it says

To create a custom start page with a similar layout as the default start page, create a table in the worksheet, add a shortcut component to each table cell and modify each shortcut component appropriately.

I'm unable to find how to insert a shortcut component.  Can someone help?

How to compute the  n component of U[i] even to reach the exact solution?



k := proc (t) options operator, arrow; t end proc:

U[0] := f(x):

for i to N do U1[i-1] := subs(x = t, U[i-1]); U[i] := (1/2)*x^2*(int(t*U1[i-1], t = a .. b)) end do:

Parse:-ConvertTo1D, "first argument to _Inert_ASSIGN must be assignable"





Exact := proc (x) options operator, arrow; cos(x) end proc





















How to find the  n component of U[i] even to reach the Exact solution cos(x)

Can the font in the Maple Component Text Area be changed? It's not obvious how to do it from "Component Properties" or anywhere else. 

Thanks, Greg.

I've used a data table component connected to an existing matrix that is updated running a loop.

However, the data table component is only refreshed after the loop, not within.

In the Data Table Properties, Enabled is on. 

What else can I do to update the table while running the loop?

I tried to use 

DocumentTools:-SetProperty("PerformanceTable", 'value', PM, 'refresh'=true);

but it doesn't seem to know 'value' as a property.

PM is the matrix it is connected to.

Here we have a very brief introduction to the use of embedded components, but effective for the study of the polynomials in operations and some products made with maple 2015 to strengthen and raise the mathematics today.

hello guys , i have a metric and i want to find its non-zero components of ricci tensor but i have problem with writing the metric and maple gave me error.

In this work we show you what to do with the programming of Embedded Components applied to graphics in the Cartesian plane; from the visualization of a point up to three-dimensional objects and also using the Maple language generare own interactive applications for touch screen technology in mobile devices techniques. Given that computers use multicore and designed algorithms that solve calculus problems with very good performance in time; this brings programming to more complex mathematical structures such as in the linear algebra, analytic geometry and advanced methods in numerical analysis. The graphics will show real-time results for the correct use of the parallel programming undertook to bear the procedural technique is well suited to the data structure, curves and surfaces. Interaction in a single graphical container allowing the teaching and / or research the rapid change of parameters; giving a quick interpretation of the results.

Hi Maple friends.

I created this table using the table component from the componwnts palette. But I can't plot it - Maple just plots the second column as horizontal lines. I want the first column to be the x values, and the second column to be the y values. How can I plot it? 

Also, the table component automatically generates the the incremental values starting from 1, so I only need to create a 1 column table. But how can I plot the table, using the auto generated values?

Thanks in advance.

EDIT: There is a 'embedded plot window' component, which may somehow plot data in the table component, but I can't get it to work. I've tried dragging the table component into it with no succes.


The Embedded Components are containers that currently use industries for modeling complex systems to find viable solutions in real time and thus avoid huge wait times and overload our computer; by this paper should show you how to implement a dynamic worksheet through Embedded Components in Maple; it goes from finding solutions to ordinary differential equations partial; which interact with the researcher using different parameters.
Using graphical programming will find immediate solutions to selected problems in science and engineering criteria of variability and boundary conditions evolving development with buttons on multiple actions.

Using MathContainer and Button for 3D vectors.

(In spanish)

i make two component that the left named MathContainer0 and right named MathContainer1

which can enter any numers on it

and i want to solve the eqution such as  

x*%MathContainer0+y*%MathContainer1=0 ,and y*%MathContainer0+x*%MathContainer1=0

but it still not shows the answers i want

anyone can help thx


How to present two indexed values a[n] and b[n] in form

a0 = ...,

a1 = ...,    b1 = ...;

a2 = ...,   b2 = ...;

in MathContainer component?


Thank you.

I have a TextArea component on the worksheet. Is it possible to create on the worksheet some number of Sliders, where the number of sliders is defined by the number entered in the TextArea?


I have a simple Maple application with two TextArea components (TextArea0 and TextArea1) inside.

The start up code is following:

Actions := module()
export DoNothing;
    DoNothing := proc()
    end proc;
end module; #Actions

the action when cotents change for both TextArea components is

use Actions in
end use;

The problem:
When I change the focus from one TextArea component to another and press Restart maple server then an error appears:

Error in Component TextArea1 with caption "TextArea": `Actions` is not a module or member.
Haw can it be fixed? Thank you.
