MaplePrimes Questions

I'm looking for any procedure to calculate orthogonal latin squares. I found this:

rOrt := proc (A, B, n)

local freq, i, j;

freq := Array(0 .. n^2-1);

for i to n do

for j to n do

freq[A[i][j]+n*B[i][j]] := 1

end do;

end do;

freq := convert(freq, list);

return numboccur(freq, 1)

end proc:

 

But I don't know what I now have to write to see result, for example for n=3?

Let $F, f_1, \ldots f_5$ be polynomials in $\mathbb{Z}_p[r,s,t,u,v]$, the ring of polynomials in 5 variables over the integers modulo an odd prime $p$. By forming the ideal $J:=<>$ I can test whether $F$ is a member of $J$. Indeed $F$ is a member of $J$ and so I know there exists polynomials $a_1,\dots,a_r \in \mathbb{Z}_p[r,s,t,u,v]$ such that $$F = a_1f_1+\dots+ a_rf_r $$ My question is how to explicitly compute $a_1,\dots,a_r$ in Maple, or Sage if you prefer. Thank...

Hello all,

 

I was wondering if the following thing is possible and how to do it:

 

I have an assignment, to teach about circles and its equations. What I want to do, is to create some sort of application, that get as input the radius and and the other two parameters of the general equation of a circle, and plots it.

Now, to plot a circle using Maple 17, is fairly easy. But how do I create a graphical bar or other alternative...

How can I Solve this using maple?

Differential equation:
y(n+2) + 7/10 y(n+1) + 1/10 y(n) = x(n)

x(n) = 1
y(0) = 0
y (1) = 1

Use Z-transformer to define y(n).

Solve y(0), y(1), y(2), y(3) y(4) and y(5) 

Any one?

Dear all,

I compute a 12,3 matrix in Maple and when I try to generate matlab code with optimization on, the result is a 36 element vector. Also, it warns me as "Warning, cannot resolve types, reassigning t15's type" and "Warning, cannot translate list". When I tried it without optimize=false it yields correct result but the file size is big. I have obtained the correct optimized resutls using Maple 13 before and hence i guess theres somthing to do with maple 17. Any...

Hi,

I have a function of n variables

y := (a,b .. n) → ....

For this function I need also n input values

y(x1,x2, ... ,xn)

The vector x has the input values ("x1,x2, ... ,xn") but how can I call them without typing them one by one?

Any ideas?

LegendreP(m-1/2, l+1/2, coth(x))/sqrt(sinh(x))

I want to calculate the series about x=0 but I get the error 

Error, (in MultiSeries:-multiseries) need to determine the sign of, 2*m

What problem does maple encounter here?

I tried assume(m>0) and then I got the error

Error, (in MultiSeries:-multiseries) need to determine the sign of, 1-2*m

Hi!

Within a for-loop I want to sum a column for a matrix, but using the column number j gives a error:

"Error, (in tools/add) bad index into Matrix"

 

script:

for j from 1 to J do

<<>>

Y[1, j] := sum('X[i,j]', i = 1 .. n)

<<>>

end do

 

Any solutions? Thanks!
