I've been working with fsolve and I'm having the following issue: fsolve({dif_Fliq=((nFsol-nFliq)/(psi_sol-psi_liq)),dif_Fliq=dif_Fsol},{psi_sol=0.1..0.9,psi_liq=0.1..0.9}); {psi_liq = 0.4447971078, psi_sol = 0.3459845910} how do I get the value of psi_liq and psi_sol and assign them to a different variable without having to copy the whole thing? i.e. if I use the following command assign(result_liq,psi_liq); I get result_liq=psi_liq = 0.4447971078 not what I want result_liq = 0.4447971078 I also tried: result_liq:=psi_liq and I ended up with the same result

I am going to export formulas from maple to plain texts like this sample ! Download 11273_plain.txt
View file details but , i confused about this simple job , please someone disabuse me , how can i do it ?

I'd like Maple to simulate airflow over a specified vehicle shape, and get it to display something similar to this.  ...

arghh.  Can't get pictures to paste, sorry.  So far I've never been able to insert a picture, haven't had the need and so haven't worried about it and now when I want to insert a picture, it's not just a straight forward thing.  Any help with that would be apprecited. 

Hello all,

Am a very new Maple user (installed today), so please bear with me! I need urgent help with the following:

I am trying to simulate polymerization of PMMA and have the following problem:

(1) I have Temperature-time data, measured experimentally.

(2) I want to fit my model which gives me a relationship between the rate of change of temperature (dT/dt) and the temperature in terms of a number of parameters:

dT/dt = Q*[Z*{exp(-E/R*T)}*{a^m}*{(1-a)^n}*{1-a}]

where,

a = P/Q + a0

Here,

Hi all first time posting on mapleprime so be nice ;) I can't seem to increase the font size of the numbers at the axis. If this is possible how do i do that? - moL

Any help you can give would be very much appreciated.

There is no released Classic interface to accompany the 64 bit version of Maple (12, 13) for the 64 bit Windows XP64 operating system. Personally, I prefer running the Standard over the Classic interface, although sometimes I miss common subexpression display for lengthy symbolic output.
 
The Maple Classic interface appears to talk to the Maple kernel only over a socket (or similar), and the...

Hi all,

I am helping a friend on this. We would like to evaluate the
convolution of

f(x)=exp(3 * x) / (1 + exp(x) ^ 5).

However, in Maple and Mathematica, using symbolic calculations, after computing the integral in closed-form, the
convolution results in numerical oscillation (lots of spikeness). We
don't know why. We just couldn't get rid of the spikeness.

Say I have the following procedure:

testproc := proc(x,y)

print(x);print(y);

x:=y;

print(x);

end proc;

And I input the following:

testproc(6,10);

Why doesn't this work? I want x to be assigned the value of why (ie, x:=10).

Hello,

I am using dsolve numeric in a for loop to run some multiple simulations. However, it looks like I get some errors due to using dsolve over and over again in the for loop.

Is there a way I can clear the memory or parameters in dsolve before proceeding to the next iteration?

Thanks,

Hi,

++++++++++++++++++

A:=Matrix(3,3);

 

ExportMatrix("A",A);

 

save A,A2;

++++++++++++++++++

 

Both 'A' and 'A2' are saved  in the same folder as the worksheet,

how can I save/ExportMatrix in a sub-folder (if folder dose not exists, creat automatically)?

 

 

Thanks.

Hello,

Please can anyone tell me if it is possible to run an executable from the Maple worksheet and how this maybe done?

Thanks,

Folarin.

How can I check if an assignment already exits?  I have a process that assigns an eqn name to the coefficients of a polynomial.  I have a number of different of polynomials that I want to do this assignment.  I have the following process:

> EqnCoeff := proc (Poly)
local n, k;
global EQN;
n := degree(Poly);
for k from 0 to n do
EQN[k] := coeff(Poly, phi1, k)
end do
end proc;

(my polynomials have indeterminate phi1)
