matlab编程中的序列翻转移位指令。

CIRCSHIFT Shift array circularly.

B = CIRCSHIFT(A,SHIFTSIZE) circularly shifts the values in the array A

by SHIFTSIZE elements. SHIFTSIZE is a vector of integer scalars (整数标锋卜量组成誉御的矢量银虚穗）where

the N-th element specifies the shift amount for the N-th dimension of

array A. If an element in SHIFTSIZE is positive, the values of A are

shifted down (or to the right). If it is negative, the values of A

are shifted up (or to the left).

Examples:

A = [ 1 2 3 4 5 6 7 8 9]

B = % circularly shifts first dimension values down by 1. B = 7 8 9

1 2 3

4 5 6

B = circshift(A,[1 -1]) % circularly shifts first dimension values down by 1 and second dimension left by 1.

B = 8 9 7

2 3 1

5 6 4

x1_shift_right1(1:10) = 0%%% 给x1_shift_right1赋初孝卜亏始值，全部为0

结果：

x1_shift_right1 =

0 0 0 0 0 0 0 0 0 0

x1_shift_right1(2:10) = x1(1:9) %%%% 将x1的第1到9个数值赋值给弊链x1_shift_right1第2 到第10个值巧神

如

>>x1=randint(1,10,[0,10])

x1 =

9 9 510 3 5 8 0 0 1

>>x1_shift_right1(2:10) = x1(1:9)

x1_shift_right1 =

0 9 9 510 3 5 8 0 0

需要链扒把时间映射到对应的数组元素的慧唤蠢序号

比如你的时间点式0:dt:N*dt

对应的数组元素的编号是1，2，3，。。。。

所以要实现kTs的位移就是把kTs/dt号前陪的元素移到第一个，一次类推
