hi

I want to get points from plot for example I have a graph like y=x but I do not know its function I want to get just some points from that like [1,1] ,[2,2] and the others but I dont know how?

the second problem which I have is I cannot show points like [1,2,2] by plot,it shows just 2D not 3D points.

I mean x=1,y=2,z=2

plot shows just 2D like x=1,y=2

thanks for your attention.

I have an BW image, which i can read in with ImageTools. now i simply want a histogram of it. the plothistogram function works, but i am not sure that it does right, because the numbers in the plot seem far to big. so i am trying to use the histogram function but i am only able to plot a histogram for a single vector of my image. is there an easy way to use the histogram function for the entire array? as the next step, i would like to compute the variance of the histogram....

Hello,

Is there a Maple procedure that generates all possible partitions of a given set? For example, for the set {1,2,3} it should give {1,2,3}, {1,{2,3}}, {2,{1,3}}, {3,{1,2}}, {{1,2,3}}.

If not, how could I write one?

Thank you!

Consider the following simple calculation with Ore algebras:

DA:=Ore_algebra[skew_algebra](euler=[theta,z]):
Ore_algebra[skew_power](sqrt(3)*theta,2,DA);
Error, (in Ore_algebra:-skew_power) skew polynomial must be member of the algebra

The error is due to the square root which is not recognized as a member of the algebra even though it is only a number. There seems to be no option to remedy this issue. Is there another solution ?

I made a model in MapleSim(Fig 1).

Here is the custom element named 'FcF' among the model. Its equation is defined as Fig 2.

I analyses
the model in Maple, the part related with the equation of FcF is shown
as Fig 3.

 I want to solve  matr.mw  for matrix A and B. Although it has 7 equations and 7 unknown parameters, but  doesnt have any result

I made a model in MapleSim 4, and an error occurred after I pushed the
button of 'simulate the model'.Maplesim froze at the step named

'CreateDataRecord: using dsolve method=rosenbrock_dae'. But it was Ok

when this file was simulated in Maplesim 3.

Is here anybody met the same problem?

question.mwWhen I sloving an exercise in my textbook using maple,I had a difficult.

First,I write the differential equation, deq:=[...];then using command,sys1:=DiffEquation(...);I want to get the system transfer function,so I use command tf:=TransferFunction(sys1),but it returns an error[Error, (in DynamicSystems:-TransferFunction) cannot handle input with frequency variable, s].

Then,since TransferFunction...

I always change text color, and I want the color in math mode to be the same as the text mode.  Is there a way to do this automatically?  The math mode always comes up in black, even if the previous text was red etc...

Thank you.

My problem that i just simlply can`t start Maple 12 under Windows 7 x64 in classic worksheet mode.

I like that much and i tried the suggested maplew.exe -cw but i got the same fancy window what i get starting just maplew.exe.

I need help and thank you.

hi, i have an equation and i cant simplify it. i claculate with hand and i know the answer but with maple i cant give answer.

       aa:= sin(theta + tao s) cos(d s) + p d cos(theta + tao s) sin(d s)

        bb:=  sin(theta + tao s) sin(ds) - p d cos(theta + tao s) cos(d s)
                 cc:=         ...

Hi,

I am not very familiar with maple but have a problem that is probably very easy for an expert. I have the coordinates of three variables, but no specific function of it. I want to create a 3d graph with these coordinates but do not know how. I have done it before with a specific function, but do not know how to do it with solely the coordinates, I work with Maple 12. Could somebody please help me, it is very important for me! thanks in advance,

Hi! I am trying to solve this system:

 but I have a problem.

Y was trying to plot this fuction f(x)=3x^2-2x when x= 0.1,.09,...,-.1 but i can't i'm a new user.

Augh, this is hurting my brain.  This homework assignment (still the same one as before) is my first experience with Maple.  I'm trying to learn the semantics of the language as I go, and that's been going well for the most part, but there's this one thing that has been bugging me to absolutely NO END:  Logical operators.

Here's what I understand after a lot of internet searching and Help browsing:
-There's two sets of very similar operators. ...
