How can I display 2 followed by 1 single animation?

ie

a:=animate(...)
b:=animate(...)
c:=animate(...)

I can animate all 3 in sequence with display((a,b,c),insequence=true)  or I can animate them all at once.  But how can I animate two at once followed by the 3rd animation?

I tried

h:=display(a,b)
g:=display(c)

gg:=dispaly((h,g),insequence=true)    Which I thought might have worked however that produces multiple frames.

Whilst I am glad that Maple have finally fixed their pdf and eps plot output with version 13 (corrupted on the Mac since version 10), I would like to re-ask the question asked by peterschmid 4 in 2006: how can I control the output size of the plot?  The plotsetup options axiswidth, axisheight, width, height, appear to have no effect.

Please note that I use Maple for academic publishing, and I wish to automatically generate graphs and export them as eps files....

As a user of Maple 13, namely in computations on General Relativity & Tensor Calculus, I would like to let you know I just got, using Maple 13, the WRONG SIGN (positive Riemann scalar curvature in stead of correct NEGATIVE Riemann scalar curvature) in studying a threefold used as a 'Public Space' by Milne many years ago.

The square of the distance on the said threefold is dE^2=dR^2+(c*t0)^2*sinh(R/(c*t0))^2*(dtheta^2+sin(theta)^2*dphi^2) and you might be interested...

Can the seq here be made into an equivalent for command?

x:=[6,2,8,4]
y:=[7,5,1,3]
stepsize:=0.5
step:=seq(min(x)..max(x),stepsize)

b:=[seq([new,min(y)],new=step)]
pointplot(b,symbol=circle,color=blue)

This is code I've converted from Matlab.  Now I'm attempting to convert the seq here into a similar but simple for loop without using seq.  There is a similar code line in Matlab using a for loop but I have no experience with...

I am gettinga string from a textfield

In my program that String represent a set of 8 bits

ie. g(t)= 10101110

But I need to separate them like

n0=1

n1=0

n2=1

...

n7=0

 

where each n is an integer

how do I do it?

 

 

 

If I assign a list to a variable named depth it causes invalid object errors in for loops for Maple12

depth:=[1,2,3,4,5,6,7,8]:

for i from 1 to 4 do
  i;
end do;

Error, invalid object: mspace(height = "0.0ex",width = "0.0em",[1, 2, 3, 4, 5, 6, 7, 8] = "0.0ex",linebreak = "newline") and  1 additional error.

 

UncertaityofCalibrat.mw

within the attached document, is the idea that I would like to develop with the optimization package.

I want to calculate iterates for the Logistic map using the maple's symbolic computation. e.g., 

x1=a*x*(1-x):

a1=a+w:

x=x1:

a=a1:

 

In order to keep track of the error that builds up in each step.  But the main trouble is that it takes very long time to calculate the same even for 100 iterates. What could be the possible method to make my program efficient ? 

Please do not answer in terms of using high precision technique as I am more interested in doing it symbolically.

 


I have the following list, vector or set, I put it in a matrix

 

 

Hello,

Does any body know why the following code

A:=Matrix(3, 3, [[-1/23*(14+21*62^(1/2))^(1/3)-31/29/(14+21*62^(1/2))^(1/3)-13/107,0,0],[0,1/22*(14+21*62^(1/2))^(1/3)+15/29/(14+21*62^(1/2))^(1/3)-13/10-1/2*I*3^(1/2)*(-1/11*(14+21*62^(1/2))^(1/3)+31/29/(14+21*62^(1/2))^(1/3)),0],[0,0,1/22*(14+21*62^(1/2))^(1/3)+15/29/(14+21*62^(1/2))^(1/3)-13/10+1/2*I*3^(1/2)*(-1/11*(14+21*62^(1/2))^(1/3)+31/29/(14+21*62^(1/2))^(1/3))]]) ;

Hi,

I'm trying to use a simple DLL in maple, which I create based on Maple external linking examples..

int __stdcall mult( int a, int b )
    {
         return a * b;
    }

and I compiled it with Visual Studio 2010 compiler, but when I use it in Maple I recieve the error

"Error, external linking: error loading external library"

thanks

Hi.  I am supposed to sketch the set of points in the complex plane defined by

|z+2|<=|z-I|

where <= is less than or equal to and I is the complex number.

By hand, we simply substitute z=x+I*y into the above inequality, expand and simplify to get

y<=-2x-1.5

From here onwards, we sketch the straight line and shade the bottom region of the line.

In more challenging cases rather than getting a straight line, one...

r(t):= <t | t^(2) | (t^(2) )/(2) >

simplify(simplify(PrincipalNormal(r(t), t, normalized), symbolic),symbolic)

diff(r(t),t)

The three lines above are part of a worksheet that computes unit tangent vector, unit normal vector and components of acceleration for a parametric curve r(t) ,  a standard Calc 3 lesson.

I am...

Hello,

I have one calculation and the result is "Length of output exceeds limit of 1000000"... What can I do with this error?

Thanks a lot.

Is it possible to specify tolerances such as +10,-5 instead of just +-10?  In other words, can the high and low limits be different?  Thanks, Ratch
