how to export data into text file
显示 更早的评论
Dear All, I am trying to export my output data from MATLAB into a text file, I attached a sample of the required FORMAT for the output file, and also the code I wrote to form the table, how can I please make it look like the output file I attached? Thank you
Month = {'January';'January';'January';'January';'January';'January';'January';'January';'January';'January'};
Class = [4;5;6;7;8;9;10;11;12;13];
Total = [100;100;100;100;100;100;100;100;100;100;];
Single = [Values_S_C4';Values_S_C5';Values_S_C6';Values_S_C7';Values_S_C8';Values_S_C9';Values_S_C10';Values_S_C11';...
Values_S_C12';Values_S_C13'];
T = table(Month,Class,Total,Single)
writetable(T,'tabledata.txt');
type tabledata.txt

Assuming that your Values_S_Cx vectors were column vectors so that Single is a numel(Total) x Ncolumns matrix, then:
writetable(T, 'tabledata.txt', 'WriteVariableNames', false);
If using R2019a, you could store your data in a cell array instead of a table, and then use writecell instead.
C = [Month, num2cell([Class, Total, Single])];
writecell(C, 'tabledata.txt');
Note that you should never create numbered or serially named variables such as your Values_S_Cx. They should have been stored straight away as just one variable.

Just for the record, storing tabular data like that in a cell array is, usually, not a good idea. Memory-wise, it's very inefficient, and will run into issues even for moderately (by today's standards) large data. Usability-wise, it's going to be very clumsy to work with numeric data, such as total, in the cell array.
But kudos for being very up-to-date with writecell!

A table, or a timetable, probably containing a mix of numeric and categroical variables.
