How to split a cell array?

Hello!

Be

Z={'1.1 2.1 3.2 3.3 5.5 5.4'; '3 4 5 10 11 56'};

a 2*1 cell array.How can I split Z into a cell array with 2x6 cells? Notice that Z is composed by numbers.

Thanks a lot.

Option One: Convert to Numeric

>> mat = [sscanf(Z{1},'%f'),sscanf(Z{2},'%f')].'
mat =
    1.1000    2.1000    3.2000    3.3000    5.5000    5.4000
    3.0000    4.0000    5.0000   10.0000   11.0000   56.0000

Best would be to leave it as a numeric array... however if you really need a cell array of numeric scalars, then use num2cell:

num2cell(mat)

Option Two: Keep as String

>> tmp = regexp(Z,'\S+','match');
>> tmp = vertcat(tmp{:})
tmp = 
  '1.1'    '2.1'    '3.2'    '3.3'    '5.5'    '5.4'
  '3'      '4'      '5'      '10'     '11'     '56'

Dear stephen

Actually my cell array is of size 10*1 cell and it goes like this:

[199001031001.000;199001031006.000;199001031011.000] [199001031002.000;199001031007.000;199001031012.000] [199001031003.000;199001031008.000;199001031013.000] [199001031004.000;199001031009.000;199001031014.000] [199001031005.000;199001031010.000;199001031015.000]

[199001031006.000;199001031011.000]

[199001031007.000;199001031012.000]

[199001031008.000;199001031013.000]

[199001031009.000;199001031014.000]

[199001031010.000;199001031015.000]

is there a way to decompose it and have each of its elements in one cell?

Becase when I use your code it says "Error using regexp All cells must be strings" which makes sense because they are not actually strings but numbers. Can you help me to solve this problem?

Thanks a lot

@angelavtc: That example with numeric vectors inside a cell array cannot be trivially converted to a single array with each numeric element in its own cell, because you have different number of elements in each vector. You could try experimenting with these FEX submissions:

http://www.mathworks.com/matlabcentral/fileexchange/33453-catpad

http://www.mathworks.com/matlabcentral/fileexchange/22909-padcat-varargin-

Note that you can supply the contents of a cell array by using a comma separated list:

inp = {[...],[...]}
out = padcat(inp{:})
