restart:

a:=0.0000000000000000000000213123123;

evalf[3](a);

I think the above is the same as if I were to change the precision tab, to display 3 decimals.

Is there a way to ask Maple to display it as  (printf(  "%3.3f",a);)

0.000

But I want this as a standard Maple ouput.

and I am not just working with a single scalar, I need something that works for a Vector, Matrix, and perhaps, in general.

Thanks,

casper

v1:=[
eta[p2] = 0.260 ,
eta[p3] = 0.113 ,
eta[p4] = -0.013 ,

]:

for i to numelems(v1) do
    printf("%a = %3.3f , \n",lhs(v1[i]),rhs(v1[i]));
end do:

This runs and returns:

w[2] = -0.447 ,
w[3] = -0.110 ,
w[4] = 0.035 ,
w[5] = 0.445 ,

Is there a way to align the qual signs? also to align the decials like this:

eta[p2]   =  0.260 ,
eta[p3]   =  0.113 ,
eta[p4]   = -0.013 ,
eta[p5]   =  0.215 ,
eta[p6]   = -0.189 ,
eta[phi2] =  0.020 ,
eta[phi3] =  0.063 ,
eta[phi4] = -0.014 ,
eta[phi5] = -0.414 ,
eta[phi6] =  0.067 ,
mu[p]     =  0.466 ,
mu[phi]   = -0.169 ,
tau[p3]   =   0.000 ,
tau[p4]   =   0.000 ,
w[1]       =   0.023 ,
w[2]       = -0.447 ,
w[3]       = -0.110 ,
w[4]       =  0.035 ,
w[5]       =  0.445 ,

For the negative numbers, I prefer to have 1 space of indentation.

hi fellas
i have questions which maybe very common but i can't handle it right now
there are 9 matrices. each one of them is a 3*3 matrix, not to say all the matrices' elements are in symbolic form.
all i want is to form a matrix made out of the 9 matrices i mentioned above in **maple**; i mean something like "cell" in MatlabI'll be appreciated for your help

Hello,

I would like to open a modelica model with MapleSIM. When I do "import modelica", I received the error message : "import failed : no library found".

I believed the modelica library was already installed on maplesim but may be not. Do I need to install modelica library ? and if yes, how ?

More generally speaking, how can I do to open a modelica model on maplesim?

Thank you for your help.

We deploy Maple to our users using Microsoft App-V; We have been using App-V 4  to successfully deploy Maple for some time. When I package Maple 18 for App-V 5 deployment, when a user launches Maple there is an error "too many levels of recursion".

After clicking OK to clear the error, choosing any of the options on the start screen, e.g. signal processing, simply launches a help screen with the message "no matches found" instead of launching a new worksheet.

App-V is our standard method of deploying applications, and has always worked OK in the past. Do you have any recommendations for packaging Maple 18 via App-V?

Thanks.

Good day,

What scheme does midrich method is using in solving BVP?

Thanks.

Hi, I would like to know if there is a command on Maple 18 that can show all the decompositions of a given symbolic tensor.

Hi,

  Excuse me, I have a following expression

x^2+x+2;

  I want to replace all x as x+1

x:=x+1 does not work.

Is there any simple solution?

Thank you very much in advance

hi,

   here are  equations like this

 sol := [abs(r)^2+abs(t)^2 = 1, r*conjugate(t)+t*conjugate(r), abs(r) = abs(t)]

when i solve this equations using command solve，the result  is none. and i used r=x+I*y,t=u+I*v in the equations,

sol:=[u^2+v^2+x^2+y^2 = 1, 2*u*x+2*v*y, sqrt(x^2+y^2) = sqrt(u^2+v^2)]

i still can't get a result.why,can you help me.

thanks.

Hi there

I am stuck with the expression

> e := (3+2*sinh(x)^2)/(sinh(x)^2*tanh(x));
                                            2
                               3 + 2 sinh(x)  
                              ----------------
                                     2        
                              sinh(x)  tanh(x)

its simplified way, which i cannot find, is

> f := 3*coth(x)^3-coth(x);
                                     3          
                            3 coth(x)  - coth(x)
> simplify(e-f);
                                      0

I would appreciate immensely if someone could give me some pointers on how to solve it.

best regards

Hi:

I will a write program in maple for plot the function f(x),while asked value n from user at first,then plot function f(x) for each value of n and finally all plots show in one figure only for different value of n,how to do it?

f(x)=1+2*(1+x)^n,x=0..5

Dear Maple Users,

I'm beginner in Maple.

I have this system of Pde:

with lambda experimental parameter and n,c,v dependent variables. I write this on Maple but I read on internet that the solution "float(undefined)" is an error.

I will insert this initial condition: c(x,0)=0,n(x,0)=0.4

Thanks everybody

Hallo,

how can I  construct a Permutationgroup with given GroupOrder and Degree.

for instance: GroupOrder 12 and Degree 5, I found by accident

G:=<(1,2,3),(1,5,2)>

Best Regards
