I have a command in Maple that looks like

Hey,

i got some linear optimization problem which i solved via maximize from the simplex library and i'd like to know if there's some way to generate only the final simplex tableau.

After typing

with(LinearAlgebra):
avector:=Vector(3,symbol=a):
bvector:=Vector(3,symbol=b):
'a x b'=CrossProduct(avector,bvector)

Maple writes out

Hi,

iam trying to define a commutator rule (using the Physics package) but iam getting an error i do  not understand.

 

I have (quantum) operators like this: A_ij  i and j are numbers from 0 to 3

The commutator relation i want to define is: [A_ij,A_kl] = A_ilδ_jk - A_kjδ_il

 

My worksheet looks like this:

 

hey friends am trying to solve non linear integral equation by using optimal decomposition method. but problem is my code is not excuting from end and my graph also not picking exact values please help me.

am attaching file please check it n let me know where am wrong.Page_No_135,_Exercis.mw

what am i doing wrong???

Error, (in pdsolve/sys) too many arguments; some or all of the following are wrong: [{u(r, t)}, {u(1, t) = 0, u(r, 0) = 0, diff(u(r, t), t) = -2}]

HI,is it possible to solve the ODE system (that I have uploaded) by adding events at a certain timestep, instead of reformulating the system for each step.The ODE system expresses two coupled movements y(t) and X(t). The current position of y(t) is controlled by a parameter which depends on values calculated in the previous step, while changing the sign for each step.Thank you!

Hello:
    I  want to get the variational value of omega when KR[N]>0.2, but  the omega of my procedure remain the same,  how do I change my program to get the variational value of omega when KR[N]>0.2.

Thank you !

My procedure:

rsolve({g(m, n) = g(m − 1, n) + g(m, n − 1)},g,'genfunc'(a,b));

why no solution

So I have this long-ish for...do...end do loop that involves all sort of things incl. running an external program (via system() ) and fitting a nonlinear expression to the result; the loop iterating a parameter for the external calculation.

It would be swell if I could run something like a progress bar that tells how many cycles done and still to go. Even better if I could get at the value of a certain variable that indicates progress of the whole calculation (which is an optimization problem...

I need to integrate the Student-T function which is a function of two variables (nu and t). Maple allows me to use this function through this command:

with(Statistics);

PDF(RandomVariable(StudentT(nu)),t);

The integration of this function gives me the probability (p) of certain event (nu is already known):

p=Int(Student,t=-infinity..X)

If I provide the value of X I can compute the integral easily, now the problem appears when I want to...

consider:

, R:  z <= sqrt(x^2+y^2+z^2)  ,  z<=sqrt(1-x^2-y^2)
what's wrong in my maple code:

>restart:

first:=int(exp((x^2+y^2+z^2)^(3/2)),x=sqrt(z^2-y^2)..sqrt(1-y^2-z^2)):
first:=simplify(first)assuming y>sqrt((z^2)/2)  ,  y< sqrt((1-z^2)/2);

I want to use a do loop to calculate some values of a function and print out the answers.
The result I want is of the form f(1)=17, f(2) = 21, etc. If I try

for j from 1 to 3 do
print( 'f(j)'=f(j) )
end do;

the j is not evalued and I get f(j)=17, f(j) = 21, etc.

I am now using Maple 15 and 16.

 

Thanks

Hi everyone, 

In my research project, I needed to evaluate a multi-variable integration.
int(int(sqrt(x^2+y^2),x),y)  , D: {(x^2+y^2 <= 2*y)  ,( y<=x ) , (x,y >0)}
