Combine two cell array of different dimension

34 views (last 30 days)
I have a two cell array A = {1,2}, B={4;5;6}
I need the result as one single array C = { 1 2 4
5
6 }
How it can be done?
Thank you

If your cell arrays only contain scalar values, why are you bothering with cell arrays instead of the much faster and easier to use plain matrices?
Furthermore, it's unclear what output you want. Note that:
C = { 1 2 4
5
6 }
is not valid matlab syntax.

A={1,2};
B={4,5,6};
C=cat(2,A,B)
C =
[1] [2] [4] [5] [6]
2 in cat is the direction you want to concatenate in, 1 does it vertically, which doesn't work because the cell doesn't have the same number of columns!

O, I didn't seee that! Must've thought it was a typo.
What you can do is:
A={1,2};
B={4;5;6};
C=cat(2,A,B')
C =
[1] [2] [4] [5] [6]
Like Guillaume said, there is no way to make a matrix or cell that's not a rectangle.

What if it’s a different number of columns and of rows?

Try this
A = {1,2};
B = {3, 5, 6};
C = horzcat(A, B)
ans =
C = {1 2 3 5 6}

I have B as 3x1 and A as 1x2. I have to concatenate in that case. Is it possible?
thank you

You should transpose one vector and then concatenate it.

A = {1,2}, B={3;4;5}
vertcat([A]',B)
ans =
[1]
[2]
[3]
[4]
[5]
