I'm not sure if u have seen this website http://mathproblems.info/working.php#s99 but i wonder if there is a better way to solve this problem using maple:

It is your task to deliever as much grain as possible from city A to city B. The cities are 1,000 miles apart. You initially have 10,000 pounds of grain. Your camel may carry up to 1,000 pounds and eats 1 pound of grain per mile traveled. You...

the eight digits of your student Id number are used to individualise the questions. they are labelled a1a2a3a4a5a6a7a8a.. all non interger outputs should be to 3 decimal places. question 1_ depending of your own value of a8, write a program that performs the calculation below:

Hello all,

I have the following generalised algebraic Riccati Equations of type:

A^TY + Y^TA + C^TC - Y^TBB^TY = 0;

E^TY - Y^TE = 0;

where A is 12x12 matrix, C is a 16x12 matrix, B is a 12x2 matrix.

However, the "CARE" function solves the different Riccati equation (http://www.maplesoft.com/support/help/Maple/view.aspx?path=LinearAlgebra/CARE)

Would you please...

Hello,

I have defined a function(say fun) to do certain task, it works well when I call it from a script file(say script1). However, when I copy the complete script1 and paste onto another script file(say script2), the function, fun, doesn't execute. It's very peculiar as my project requires lot of modification, so I copy the old script and...

If S= { <0,1>,<1,2>} and T={<1,1>,<2,3>} are ordered bases for R² and v=<1,5> and w=<5,4>, then can someone help me:

-find the coordinate vector of v and w with respect to the basis T by creating a procedure?

-I can make a procedure to find the transition matrix P_S<-T from T to S-basis, but can you help find the coordinate vector of v and w with respect to the basis S. Using P_S<-T?

Dear Mapleprimes,

I am trying to solve an Optimization problem analytically. I set up a lagrangian as follows:

L:= Objective function + mu_1 (constraint 1) + mu_2 (constraint 2)

I maximise with respect to two variables, call them x1 and x2

I want constraint one to bind but not constraint 2. Hence, I set mu_2=0. The I do:

diff(L,x1); diff(L,x2), diff(L,mu1), diff(L,mu2)

Hi,
I'm trying to import matlab function from m-file.

File looks like this:

    function out = xxx(omega)
    out = heaviside(omega);

It's only heaviside function.

And now, when I'm using "FromMFile" command in Maple it doesn't recognize Heaviside function. It imports that function as "heaviside" - witch small first character (in Maple we needs big "H").

Any help? 

thx 

Hello, I'm creating a rolling thin disk (rolling without slip) in the MapleSim, the model like the picture below (Fig. 1).

       ...

I need to make one "DensityPlot-point" (similar Statistics [DensityPlot] or histogram in 

Matrixplot) of a set of points (x, y). 

The set of points (x, y) was generated by the procedure.

Is there a way to generate it?

Thank you.

Please help me plot the graphs of the following equations:-

eq1 := diff(E[X(t)], t) = lambda-delta*E[X(t)]-beta*E[X(t)*V(t)];

 eq2 := diff(E[Y(t)], t) = -delta*E[Y(t)]+beta*exp(-rho*tau)*E[X(t)*V(t)];
                                                    
eq3 := diff(E[V(t)], t) = gamma+N*kappa*E[Y(t)]-mu*E[V(t)]-beta*E[X(t)*V(t)]

NB:- E[X(t)]= the expected value of variable X at time t. 

Please help me know how to input this...

Hello colleagues! :)

I have some problems after create two objects, with array row in object definition...

The result - two same object...

How can i solve for X(t) in the following equation

diff(mean(X(t)), t) = lambda-delta*mean(X(t))-beta*mean(X(t)*V(t))

and how can i plot X(t) against t.

I have a program in  matlab,

I want to change below code in maple,

henon_map = inline('[a-x.^2+b*y x]','a','b','x','y');

%a=input('a [0] = ');
b=input('b [0.4] = ');

%if(isempty(a))
% a=0
%end

if(isempty(b))
 b=0.4
end

Npts=200;
Ntrans=100;
Ntot=Ntrans+Npts;

% For the whole window:
fig1=1; fig2=2;xmin=-2;xmax=2; Nmin=1; Nmax=50;
amin = -0.09;
amax = 1.249;

Branched from huffman coding (excellent example).  The huffman tree was not encoded in the message. The tree was known from the original message but suppose we didn't have the original message.  We need the tree in the compressed message.

How do you include the huffman tree in the message?

Every time i open an already saved document and change it then try to save it it comes up with this error:cwmaple.exe has stopped working!!! Why does this happen??

Please Help

Thanks,
