I have an csv file with column headers (strings) and data. I then want to add a new column with a specific header 'My new header' and data is stored in a 100x1 double variable called myNewData. How I can add a new column with header 'My new header' and values of the column be myNewData?

推荐答案

我能够使用Matlab中的表，仅用三行代码来做到这一点，如下所示:

I was able to do this using tables in Matlab in just three lines of code as shown below:

table = readtable('myfile.csv','Delimiter',',');
table.class = newcol; %where class is the name of the header of the new column and newcol is a variable which has my new column data
writetable(table,'myfilenew.csv','Delimiter',',','QuoteStrings',false)
