I need to create a (m + 1)*n cell matrix concatenating a cell array of strings named NomiDopo with a m*n matrix of double, DataSet. The final result must be a (m + 1)*n cell matrix of string, otherwise the xlswrite function does not write the correct values in the output spreadsheet. This means converting the original matrix of double DataSet into a matrix of string. I tried in many ways, also using the mat2cell function, but it didn't work. Can anybody help me, please? Thank you!

Are you using xlswrite? This function accepts mixed data in a cell array, have you tried using this? What happens that you do not expect? Are the values represented incorrectly?

You can use num2str inside arrayfun to convert numeric values to a cell-array of strings:
>> A = {'header_1','header_2'};
>> B = [0.1,2.3;4.5,6.7;8.9,NaN]
B =
0.1000 2.3000
4.5000 6.7000
8.9000 NaN
>> C = arrayfun(@num2str,B,'UniformOutput',false)
C =
'0.1' '2.3'
'4.5' '6.7'
'8.9' 'NaN'
>> [A;C]
ans =
'header_1' 'header_2'
'0.1' '2.3'
'4.5' '6.7'
'8.9' 'NaN

Stephen, thank you so much!!!! It worked! What happened before is that if I used xslwrite with mixed data, then it didn't work and the ouptup was a spreadsheet with nothing inside. Thank you very much again! Best,

Strange, as xlswrite should work with mixed data (it states this explicitly in the documentation). Can you show exactly how it was being used? It would be interesting to see the data (either upload a .mat file or as text within a comment).
