Hi,
correction for "end":

>> help end
END Terminate scope of FOR, WHILE, SWITCH, TRY, and IF statements.
Without END's, FOR, WHILE, SWITCH, TRY, and IF wait for further
input.
Each END is paired with the closest previous unpaired FOR, WHILE,
SWITCH, TRY or IF and serves to terminate its scope.
END can also serve as the last index in an indexing expression. In
that context, END = SIZE(X,k) when used as part of the k-th index.
Examples of this use are, X(3:end) and X(1,1:2:end-1). When using
END
to grow an array, as in X(end+1) = 5, make sure X exists first.
END(A,K,N) is called for indexing expressions involving the object A
when END is part of the K-th index out of N indices. For example,
the expression A(end-1,:) calls A's END method with END(A,1,2).
See also FOR, WHILE, SWITCH, TRY, IF.
>> a=1:10;
>> a(1:end)
ans =
1 2 3 4 5 6 7 8 9 10
>> end
Warning: Unmatched "end".
>> which end
end is a built-in function.

For me it seems, that you either
o have an old matlab version (4.0)
o or something else
"end" is a valid 'function/value'.
