convert a string to a cell in matlab

I have a column vector of integers and I want to convert it into cell in matlab. The following is the code. But it did not output what I expected. 

nodes = [10; 21; 44];
nodes = num2str(nodes)
nodes = num2cell(nodes)

nodes =

10
21
44


nodes = 

    '1'    '0'
    '2'    '1'
    '4'    '4'

Can anyone help me fix this? Many thanks for your time and attention.

Another way is to use arrayfun (i.e. a wrapper for a for-loop):

arrayfun(@num2str, nodes, 'uni', 0)

or if you want numbers in the cells (not strings) then it's just

num2cell(nodes)

i.e. without the num2str

In the third line's argument, nodes is a string and not a number anymore.
Therefore you can use the cellstr-function to convert the string-array to a cell-array of strings.

nodes = [10; 21; 44];
nodes = num2str(nodes)
nodes = cellstr(nodes)

This outputs:

nodes =
10
21
44

nodes = 
    '10'
    '21'
    '44'
