## Fundiff with anticommuting functions...

Maple

Hi everybody,

during testing the physics package I tried the following example

with(Physics):

Setup(anticommutativeprefix = {Q});

G:= Intc(Q1(x),Q2(y),x,y);

Fundiff(G,Q2(u));

The output of the last command seems to be wrong. The Maple Help does not say anything about functional derivatives with respect to anti commuting functions.

Is there a possibility to perform such functional derivatives with respect to anti commuting functions in Maple?...

## Numerical integration of procedures...

Maple

Hi,

somehow Maple does not integrate a procedure in the correct way. And I don't know why. Could you please help?

This procedure creates a matrix of a special form

P:=proc(n,k,A,d,Lambda)

local p,i,j,m,off,eps:

if n<6 then print("n greater 6"): return: end if:

if (n mod 4)<>2 then print("n has to be n (mod 4) = 2 "): return: end if:

eps:=proc(m,A,Lambda,k) (k+m*Lambda*2)^2+A/2 end proc:

## MathieuExponent...

Maple

Hi,

where can I look up, how Maple calculate the function MathieuExponent. By how I mean, which algorithm is used by Maple and how is it implemented,

Thanks
