a(i)等于x对3取余数，
mod的例子如下：
>> mod(3,3)
ans =
0
>> mod(5,3)
ans =
2
>> mod(1,3)
ans =
1
mod的详细解释如下：
>> help mod
mod Modulus after division.
mod(x,y) is x - n.*y where n = floor(x./y) if y ~= 0. If y is not an
integer and the quotient x./y is within roundoff error of an integer,
then n is that integer. The inputs x and y must be real arrays of the
same size, or real scalars.
The statement "x and y are congruent mod m" means mod(x,m) == mod(y,m).
By convention:
mod(x,0) is x.
mod(x,x) is 0.
mod(x,y), for x~=y and y~=0, has the same sign as y.
Note: REM(x,y), for x~=y and y~=0, has the same sign as x.
mod(x,y) and REM(x,y) are equal if x and y have the same sign, but
differ by y if x and y have different signs.
