Save a string vector as csv in matlab - arrays

Question

I have the following string array in matlab built the following way:
labels=textread(nome_tecnicas_base, '%s');
for i=1:size(labels)
temp_vector=cell(1,10);
[temp_vector{1:10}]=deal(labels{i});
final_vector=horzcat(final_vector,temp_vector);
end
I want to save this vector with each string value separated with commas (e.g., csv files) in a text file. I tried in several ways, but when I try to read it with, for example, the textread function i have the following error:
a=textread('labels-cpen-R.txt')
Error using dataread
Trouble reading number from file (row 1, field 1) ==> dct,dct,dct,dct,dct,dct,dct,dct,dct,dct,hierar
this is how my file was saved

How can I save this vector and how can I read this file properly?

Answer 1

try textscan for reading and fprintf for writing
from the matlab documentation:
fileID = fopen('data.csv');
C = textscan(fileID,'%f %f %f %f %u8 %f',...
'Delimiter',',','EmptyValue',-Inf);
so in your case:
textscan(fileID,'%s', 'Delimiter', ',')
edit: for writing data to a file, you can use fprintf with a file identifier:
fileID= fopen('data.csv', 'w') ;
fprintf(fileID, '%s,', data{1,1:end-1}) ;
fprintf(fileID, '%s\n', data{1,end}) ;
fclose(fileID)
