Merge datetime with another cell for export
显示 更早的评论
How do I combine two matrices of different types? I have a datetime matrix and one with pH values, and I would like to export them in one .csv file from matlab. When I try to merge them I get the error message "All inputs must be datetimes or date/time character vectors or date/time strings."
Is there a way to merge datetime with other cell matrices, and how is it done?

writecell (as well as the various other builtin solutions) has the problem that the date string contains embedded blanks but is not quote-delimited. This means reading the file back in generally takes extra steps to keep the date and time from being broken apart into two variables.
To prevent this, use (what I think should be default instead of not) the 'QuoteStrings' parameter:
>> writecell(c,'C.csv','QuoteStrings',true)
>> type C.csv
"25-Jun-2020 08:22:52",3.14159265358979
