我有數據在Excel中是這樣的:使用MATLAB安排Excel數據
id date value
a 9/17/2012 0.25
a 9/18/2012 0.48
a 9/19/2012 0.29
a 9/20/2012 0.46
a 9/21/2012 0.17
a 9/24/2012 0.89
a 9/25/2012 0.20
a 9/26/2012 0.65
a 9/27/2012 0.26
b 9/17/2012 0.83
b 9/18/2012 0.87
b 9/19/2012 0.40
b 9/20/2012 0.33
b 9/21/2012 0.71
b 9/24/2012 0.13
b 9/25/2012 0.91
b 9/26/2012 0.73
b 9/27/2012 0.87
c 9/17/2012 0.47
c 9/18/2012 0.15
c 9/19/2012 0.73
c 9/20/2012 0.47
c 9/21/2012 0.03
c 9/24/2012 0.23
c 9/25/2012 0.21
c 9/26/2012 0.39
c 9/27/2012 0.77
,我想用Matlab來重新安排:
date a b c
9/17/2012 0.25 0.83 0.47
9/18/2012 0.48 0.87 0.15
9/19/2012 0.29 0.40 0.73
9/20/2012 0.46 0.33 0.47
9/21/2012 0.17 0.71 0.03
9/24/2012 0.89 0.13 0.23
9/25/2012 0.20 0.91 0.21
9/26/2012 0.65 0.73 0.39
9/27/2012 0.26 0.87 0.77
怎樣做最簡單的方法這個?
