I am working over F_p, where p is prime. When p = 2, the number of 2x2x2 arrays (aka hypermatrices or tensors) over this field is 2^(2*2*2) = 256. Of those 256 arrays, I only want the symmetric ones: that is, if x_{ijk} is the ijk-th element of the array X, then x_{ijk} = x_{ikj} = x_{jik} = x_{jki} = x_{kij} = x_{kji}. Is there a quick loop that does this? 

Hi, I would like to solve for i and c in this system. But whenever I try to solve it, it give a warning message "the solution may have been lost"

Hey everybody,

I'm tring to display text plots with lines and points. When I use the display command and change the size of the display, the font size does not change with it. Is there any way to have the plotted text to change size with the display?

Thanks,

I am trying to overload the "." operator (noncommutative product) to handle objects I have implemented as records. Each record contains a matrix R and a parameter l. A.B will produce a new record where l is l_A+l_B and R is R_A.R_B, "." here being the normal matrix product (and I use LinearAlgebra:-Multiply in the body of my procedure for this). The objects A and B are of type 'Element', which I have defined (using AddType) and which works.

I implemented the procedure...

Hi all,

I need your kind suggestion to solve the equation for odd ratio.  I am attaching Maple file for the purpose.   I have to evaluate a function for odd ratio and for other values its zero.  I need help in assigning this odd and even ration to the function.  k can vary from 1...15, depending on ratio.

I shall be very thankful for your kind responses.

what is the window use for maple 16: vista, xp, or win 7?

Question 1. After googled, x*diff(F,t)+t*diff(F,x) for two variables, how about three variables or general ?

Question 2.

if deal with on variables case using the example in

http://demonstrations.wolfram.com/AFunctionInvariantUnderAGroupOfTransformations/

F := (x^2-x+1)^3/((x^2)*(x-1)^2)-y;
G:=y*diff(F,x)=0;
sol:=solve(G,y);

F(H)-F = 0
sol:=solve(F,x);
H := simplify(subs(y=F, sol[1]));

all above code can...

Hi all,

I am trying to solve the equation for values k=1 to 10,  but the issue is when I put k=1 equation goes to infinity.  I am attaching Maple file for your kind consideration.  I have also included an example which may help you to answer.  I couldn't understood how its done.

Hello! I am running the same piece of maple code on different machines, and I have noticed that the powerset function returns the sets in a different order. For example,

Maple 11 (X86 64 LINUX)

> powerset(3);
            {{}, {1, 2, 3}, {2, 3}, {3}, {1, 3}, {1}, {2}, {1, 2}}

Maple 14

> powerset(3);
            {{}, {1}, {2},...

Hello Maple experts,

 I want to find out k-th probability (denoted by c(k)) which is expressed as an integration of summation for values ranging from j=0 to k. The function is very complicated , I have attached the PDF for expressing the mathematical term properly.

I am able to find out the c(k) for a given value of k, if k is specified in the beginning of the maple program. But I am unable to make it generic form of k.

I have also attached the...

Hi all,

I am stuck in defining two conditions for the equation.  I am attaching Maple file for your kind consideration.

Actually I want to assign the value of k=1, and when k is not =1, for G11(k).

I shall be very thankful for your kind replies.

hi

consider the following ode

eq1:=diff(f(x),x$3)+f(x)*diff(f(x),x$2)+diff(f(x),x$1)^2;

subject to thease boundary condition

f(a)=0,D(f)(b)=0,D(D(f))(0)=0

where

b= infinity (in computational domain b=10 is acceptable )

the exact solution of ode is

f(x)=tanh(x/2)

but when i want to solve it with Dsolve, maple get the zero. how can i use this ode in maple

thanks

I am a transplant from to Mathematica to Maple and still getting used to things. Could somebody please help me finding the maximum of f with repect to the constraints and with the variables below. I keep getting  syntax error, no matter how many times I check the documentation page. Thank you very much

hi dear

what is this error and how i can fix it?

Error, (in gcd/NoExpandDegreeCheck) inputs must be polynomials over all variables
