Help: "Error using horzcat, CAT arguments are not consistent"

So I have two data sets, a and b.

a = [1 
     2]

b = [20 30]

I used transpose to make b in a column as well...

x = a;
y = b';
[x,y]

However, when I try to use [x,y] it gives me the horzcat error.

I typed whos x y just to make sure they were the same size after transposing b, and sure enough:

    >>whos x y
      Name      Size            Bytes  Class     Attributes

      x         2x1               126  cell                
      y         2x1                16  double

Given that they are both 2x1, I don't understand why I'm getting this error!

Any help would be appreciated. Thank you!

Why does it say that x is cell rather than double? You must have done something else to "x".

Your difficulty has to do with the rules for concatenating cell arrays together with numeric arrays: basically if you want to concatenate together a cell array and a numeric array, the cell array must be a vector.
