年夜家好，小活来为年夜家解答以上题目。matlab取整函数，matlab取整良多人还不知道，此刻让我们一路来看看吧！
1、 批改-四舍五入到零。
2、 fix Round towards zero.
3、 fix(X) rounds the elements of X to the nearest integers
4、 towards zero.
5、 利用fix的示例：
6、 t=
7、 7.6806 3.5388 3.6130 9.0150 8.1769 3.1781
8、 2.3309 3.4719 7.4163 3.1834 9.8118 9.8445
9、 5.8736 2.5372 7.0590 5.9708 8.6199 5.4825
10、 4.5897 9.5253 7.0089 2.9780 0.8382 7.4925
11、 8.6098 2.9820 0.0623 1.2501 3.3771 8.4185
12、 6.6084 1.5841 3.7435 3.8836 2.3613 1.6689
13、 -----------------------------------------------------------------------
14、 fix(t)
15、 ans=
16、 7 3 3 9 8 3
17、 2 3 7 3 9 9
18、 5 2 7 5 8 5
19、 4 9 7 2 0 7
20、 8 2 0 1 3 8
21、 6 1 3 3 2 1
22、 绕到比来的标的目的。
23、 round Round towards nearest integer.
24、 round(X) rounds the elements of X to the nearest integers.
25、 地板-四舍五入至负无限年夜：
26、 floor Round towards minus infinity.
27、 floor(X) rounds the elements of X to the nearest integers
28、 towards minus infinity.
29、 舍入到正无限年夜。
30、 ceil Round towards plus infinity.
31、 ceil(X) rounds the elements of X to the nearest integers
32、 towards infinity.
33、 Mod-计较模数：
34、 mod Modulus after division.
35、 mod(x,y) is x - n.*y where n=floor(x./y) if y ~=0. If y is not an
36、 integer and the quotient x./y is within roundoff error of an integer,
37、 then n is that integer. The inputs x and y must be real arrays of the
38、 same size, or real scalars.
39、 The statement 'x and y are congruent mod m' means mod(x,m)==mod(y,m).
40、 By convention:
41、 mod(x,0) is x.
42、 mod(x,x) is 0.
43、 mod(x,y), for x~=y and y~=0, has the same sign as y.
44、 Note: REM(x,y), for x~=y and y~=0, has the same sign as x.
45、 mod(x,y) and REM(x,y) are equal if x and y have the same sign, but
46、 differ by y if x and y have different signs.
本文到此竣事，但愿对年夜家有所帮忙。
