# how to creating new matrix which is the variables come from 2 different matrix..?

Asked by Noru on 16 Apr 2013

I have a little matrix problem which perhaps interesting for you. Here it comes :

I have 2 matrix like below :

```A = 8     1
9     3
1     5
9    10
6    10
```
```B = 0.1576    0.1419
0.9706    0.4218
0.9572    0.9157
0.4854    0.7922
0.8003    0.9595
```

And i want to join those two matrix and separate each line of those two matrix above become 5 different matrix with loop process, like below :

```C(1) = 8   0.1576
1   0.1419
```
```C(2) = 9   0.9706
3   0.4218
```
```C(3) = 1   0.9572
5   0.9157
```
```C(4) = 9   0.4854
10  0.7922
```
```C(5) = 6   0.8003
10  0.9595
```

I am a rookie in matlab and still need an assist for some matlab problem from every pro in this forum.

Anyone have the solution..?

thank you..

```C = permute(cat(3,A,B),[2 3 1])
```

in cell array

```Ccell = reshape(num2cell(C,[1 2]),[],1);
```

with for-loop

```C2 = cell(size(A,1),1)
for jj = 1:numel(C2)
C2{jj} = [A(jj,:);B(jj,:)]';
end
```

when i using your loop operation why it just created matrix like below :

```C2 =
```
```    [2x2 double]
[2x2 double]
[2x2 double]
[2x2 double]
[2x2 double]```

Am I doing mistake..?

No, try below:

```C2{:}
```

or

```C2{1}
```

ok thank you for your help.. it really works..

You could have your 2x2 matrices as sheets C(:,:,i) of a 3D array, just by doing

` C=reshape([A,B].',2,2,[])`
