How can I create a cell array by combining arrays?

1 次查看(过去 30 天)
Lets say;
names=['X1','X2','X3']
first=[1 2 3]
second=[4 5 6]
third=[7 8 9]
I need a cell array that is combination of these four arrays. It should be 1x4!
cellArray={['X','Y','Z'],[1 2 3],[4 5 6],[7 8 9]}
How can I write that code. horzcat is no good. Thanks!

Note that
names=['X1','X2','X3']
is the same as
names='X1X2X3'
Therefore I cannot guess, what you want as output and how your input exactly should look like.

maybe this? mat2cell
it is unclear what you are trying to accomplish with the cell conversion, so this is the best I can do.

What are you having trouble with? The code you posted works.
>> cellArray={['X','Y','Z'],[1 2 3],[4 5 6],[7 8 9]}
cellArray =
1×4 cell array
'XYZ' [1×3 double] [1×3 double] [1×3 double]

Oooh, string arrays are uncomfortable in MATLAB. Either do {'X','Y','Z'} or make a table() instead of a cell array.
['X','Y','Z'] is the concatenate constructor for strings, not an array.

Billie Jean, please read the FAQ on cell arrays. I think it will help you understand. http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
With ['X','Y','Z'] you are concetnating 3 single characters to form a 1-by-3 character array, also known as a string. They are the same thing. In fact you can also set it to 'XYZ' and get the same thing. Just look:
>> s=['X','Y','Z']
s =
XYZ
>> whos s
Name Size Bytes Class Attributes
s 1x3 6 char
>> s='XYZ'
s =
XYZ
>> whos s
Name Size Bytes Class Attributes
s 1x3 6 char
Now, that string is inside the first cell of a 1-by-4 cell array. A single cell, like the first one , is a 1-by-1 array if you want to look at it that way. But because it's a cell, it can contain virtually anything inside it. And in this case, that first cell contains a 1x3 string (character array) inside it. Think of a cell like a bucket, and a cell array as an array of buckets. You can throw anything you want into the buckets: a string, a double array, a structure, a table, even another cell or cell array. Different buckets can contain anything - you're not required to have a whole column or whole row have the same data type in it. You can vary the contents of the buckets on a bucket-by-bucket basis. Again, read the FAQ - you won't regret it.
