问题
I have a cell array myFile 637x16. The first row of the cell array is made of strings, because they will be the columns' labels in the .xlsx/.csv file.
From the second row on, the cell array is made of some columns with strings, and some columns with numbers. I would like to export this cell array as a .xlsx or .csv file.
Here is an example of what I have:
'subject' 'PeakA' 'PeakL' 'number' 'epoch' 'code' 'type' 'latency' 'nitem' 'condition' 'ia' 'cover' 'variety' 'init_index' 'init_time' 'urevent'
5 3.50 82 13 1 201011 'pre' 2502 201 1 1 'y' 'h' 13 13.92 13

5 1.45 51 199 8 212011 'pre' 42479 212 1 1 'y' 'h' 199 190.96 199
I tried:
xlswrite('filename.xlsx', myFile);
but it gives me this error:
Warning: Could not start Excel server for export.
XLSWRITE will attempt to write file in CSV format.
> In xlswrite (line 174)
Error using xlswrite (line 187)
An error occurred on data export in CSV format.
Caused by:
Error using dlmwrite (line 112)
The input cell array cannot be converted to a matrix.
回答1:
If you have a sufficiently recent version of Matlab (R2013b or older), writetable is your friend.
%# create a table
tbl = cell2table(yourCellArray(2:end,:),'variableNames',yourCellArray(1,:));
%# write to file
writetable(tbl,'filename.xlsx')
If you want to use xlswrite, it may be worth converting all data to string first, or to write the variable names separately, before you write the rest - I believe Matlab checks data types on the first row, which can cause typecast errors.
