how to concatinate two array values in one array
显示 更早的评论
Suppose i have two arrays
A1=
1
2
4
7
9
12
21
A2 =
10.21 32.31
43.54 30.12
41.32 59.21
47.11 43.94
95.5 93.2
86.32 90.2
12.33 57.65
now i wish to make another array which store both array values acording this order
A3=
A1 A2
1 10.21 32.31
2 43.54 30.12
4 41.32 59.21
7 47.11 43.94
9 95.5 93.2
12 86.32 90.2

Nothing is removed from the values, but being in a matrix vs being just a scalar can alter how the number is displayed. E.g.,
>> A = 1
A =
1
>> B = 1e-5
B =
1.0000e-05
>> C = [A B]
C =
1.0000 0.0000
>> C(2)
ans =
1.0000e-05
>> format long g
>> C
C =
1 1e-05
>> format short
>> C
C =
1.0000 0.0000
You can see from the example that the 1e-5, when first made part of the C matrix, displayed as 0.0000. But that is just an artifact of the short display format. The number hasn't changed or been truncated in any way, as can be seen by just displaying C(2) by itself, and by changing the display format to long g.
