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)

Hi

I'm trying to use maple on a Dell with intel video chipset series 4, on a Fedora 11, and I get corrupted 3d graphics. I read this FAQ http://www.maplesoft.com/support/Faqs/detail.aspx?sid=33530

(point 3) but it seems that no solutions exist.

I'm using the intel driver, this is the sheet of xorg.conf

 

Given 3 cylinders:

x^2+y^2=1

x^2+z^2=1

y^2+z^2=1

How would I go about plotting the intersectioin and only the intersection?

Thanks you!

I was wondering is it possible to make a procedure in maple that works out the Bisection, tri section using a single procedure?

So for example for the bisection method c : =( a + b ) /2
fAnd  trisection method c : = ( 2 * a + b) / 3 and d : = (2 * b + a )/3 etc

For n th section L [ i ] :=( i*b + a ( n - i ) ) / n:
` i ` represents the position in a List.

e.g (Not sure if it would work in a proc)
Trisection
n:=3:
i:=1:
L:= [ c , d ]:

L[ 1 ]:= ( b + 2 * a ) / 3:

How would I express cos(2x+(Pi/6)) in the form Acos(2x)+Bsin(2x)? Also I have plotted y=(x^2-4x+5)/(x-2) I need to mark vertical, horizontal or oblique asymptotes with a dashed line. Determine the location and nature of any turning points. Does anyone know how to do this? Please help, thank you. Chloe

Hi... I don't have a lot of experience with Maple, but I want to plot some test data and find a least squares curve fitting. I know how to plot the stuff I want to plot, and how to do basic least square fitting. However, I have 6 data points to apply least squares on, and I have one additional "fixed" point. I know the curve will have to become parabolic (And I know how to curve fit to that using LeastSquares), but the problem is that the minimum of that parabola has to go through the fixed point. I have no idea how to achieve this (if it is at all possible).

Find y(1) and y′ (1), and then plot y(x) and y′ (x) on the same graph over
the range 0
≤ x ≤ 1, if y(x) is the solution of the initial-value problem corresponding
13
to the differential equation y′′ + sin(xy) = 0 and the initial conditions y(0) = 1 and
y′ (0) = 2.

 

That's my question, here's my input so far.

who know how can i solve or plot a two unknowns equation in MATLAB like implicitplot in maple?

Hi

I've got some problems with the upper limit of an integral, which is a (known) function of a parameter.

When I try to evaluate it for a particular value of the parameter (M), Maple does nothing:

 

Hi I'am using a simple method to simulate solutions of ODE's with a precision that requires to do 80 million evaluations of my functions. Since this does thake a while, I was wondering if it would be possible to display some type op progress bar or to show on the screen how many steps have already been done. Is it possible to do this inside a proc environnement? Thanks in advance Pieter

I cannot find the Statistics Phi. For example when z is 0 Phi(z)=0.5 When z=0.50 Phi(z)=0.6915 I cannot find this anywhere in Maple. It's the Cumulative distribution function of the standard normal distribution Φ(z)

I am just curious as to how much money my fellow mathematicians would consider to sufficient to pursue a Martingale betting strategy? I would suspect that 20 000 ( assuming an initial betsize of 1) would be sufficient. Then you can handle 13 sequential losses.  However, it is a bit risky because let say you get 14 sequential losses then you will lose all 20 000 , he he

 

 

I copy the "lim" command in the Help,it seems doesn't work easily,what should I do make it work,
