I have some data I would like to write them in csv file but I am getting erros regarding the fprintf as well as I can get the right decimal places that I wrote. [ Please see the code below ].
fid=fopen('mn21hmya2021.csv','wt');
fprintf(fid,'time_q2,reach,x_relative_hand,y_relative_hand,z_relative_hand\n');
fprintf(fid,'%.2f,%.4f,%.4f,%.4f%.4f\n', wanted_columns');
fclose(fid);
headers = {'time_q2','reach','x_relative_hand','y_relative_hand','z_relative_hand'}
write= array2table(wanted_columns, 'VariableNames', headers)
writetable(write,'mn21hmya2021.csv','Delimiter',',')
The errora are:
1- Invalid file identifier. Use fopen to generate a valid file identifier.
2- fprintf(fid,'time_q2,reach,x_relative_hand,y_relative_hand,z_relative_hand\n');

The folder might be write protected. Check this in general:
[fid, msg] = fopen('mn21hmya2021.csv','wt');
assert(fid > 0, msg);
Prefer absolute path names. It is fragile to rely on the current path to be at an expected location.

Fine. This means, that you do not have write permissions in the current folder. What is the current folder? See the output of the cd command.
