You did not explain how the file should look like. If you want a binary file to read it later in Matlab, use SAVE. For a text file with tabs as separators:
A = {'cell';'gene';'protein';'DNA';'RNA'};
B = {'cycle';'regulation';'structure';'replication';'editing'};
C = [1;2;3;4;5];
CC = num2cell(C, 2);
Data = transpose(cat(2, A, B, CC));
FID = fopen('FileName.txt', 'w');
if FID == -1, error('Cannot open file'); end
fprintf(FID, '%s\t%s\t%d\t\n', Data{:});
fclose(FID);
If you want something else, explaining the details is required.
