Hello. I seek advise regarding plots. My query is: Is it possible to change the center of a plot in Cartesian coordinates from the default (0,0,0) to another set of values? Would greatly appreciate prompt advise. Best regards, wirefree

How can i plot "Direction fields"and"integral curves of Diffrential Equtions?

how to solve/plot a set of nonlinear inequalities for 2 variables in Maple 10?

I would like to animate a curve against a background of a rectangle, i.e. four lines  I know how to make a background of a plot but I can't seem to use the line command in place of a plot command.  Moreover, I need four lines, not just one.  How do I make multiple lines as a background?

Thanks.

I constantly need to run a part of my code. I define that part as a proc. But each time, I need to check all the variables appears inside the proc are declared as global, otherwise the output will be ruined. I figured if I can set the implicitly declared type in a proc as global then things will become simple.

Hi,

I am designing an antenna based on Peano-Gosper fractal. I have limited math skills and the most difficult part for me is deriving the generator for this fractal that takes two points (beginning and end) of initiator and generate 8 points PG curve consisting of 7 segments. Could you please suggest where I can find such generator written in Maple?

Thank you very much Vadim

hi there ! i wrote this in maple: for i from 0.86 by 0.01 to 2 do print(fsolve({x1+x2 = i, -3*x1+4*x1^3-3*x2+4*x2^3 = 0}, {x1 = 0 .. 1, x2 = 0 .. 1})) end do it computes the values of x1 and x2 and print them . but i want to store these values and the corresponding value of i in two separate arrays i.e. one array having values of x1 and corresponding i ; and the other array having values of x2 and corresponding i. and at last i want to plot the points in both arrays on the same graph so that i have a curve for x1 and x2 both on the same plot having i on its x-axis.

Dear all,

 

I am having some problems with the coeff() function in Maple13. I first defined a function "functie3";

> functie3;

 

When i try to obtain the coefficiënts from t2, t2^2, t2^3, t2^4 and the constants i always get the following error:

> coeff(functie3, t2, 2);

Error, unable to compute coeff

 

Could somebody help me out with this? Any help is greatly appreciated!!

 

Best Regards,

I try to find a way to tell maple to use a specific value (e.g. zero), if the function is not real i.e. not defined, or complex etc.

Actually I want to find out, where a specific function is not defined, or has no real value. Is that possible with Maple?
Anyway, if there is no way to find out, where a specific function has no real value, I want to apply a specific real value to any value of the function, which is not real.

For example I tried the following:

Hello! I have a problem - i can't find standart Maple functions and procedures, that plot, so to speak, "phase portrait"-esque magnetic field lines for featured "vector field". In details: i need to plot magnetic field lines and equipotential curves of uniformly magnetized cylinder. I have piecewise functions Hr(r,z) and Hz(r,z), (per se, r is x, z is y, y-axis coincides with cylinder axis): L := 2; a := .5

Hi,

I read data into Maple, and based upon that, wish to dynamically construct a piecewise function. In advance, it is unknown how many entries the piecewise will have or where the breakpoints are.

How can I work dynamically/programmatically with piecewise functions? Is there some documentation or concept I should know about so I can help myself on this? The only possibility I've found thus far is using the sscanf function, which makes it a little more complicated than necessary.

Hey i am trying to get maple to do some differential equation solving and i am running into some major road blocks.

the code i am using is as follows:

restart;

M[Star] := 2*10^30;

M[planet] := 2*10^27;

q := M[planet]/M[Star];

g := sqrt((R-a)^2);

H := 0.333e-1*R;

Delta[p] := H;

Hi there,

The bloggers at Maplesoft.com have been busy recently, and we've seen the addition of some great new posts.  Here are some links if you're interested.
