add labels to columns

12 views (last 30 days)
I have a 'q' which is a 150 by 10 matrix (150 rows each with 10 variables).
when I look at the data in variable editor, (where its like an spreadsheet view of the data) I get the columns labeled 1,2,3,...,10.
How can I change this? How can I get the columns to have descriptive text as headers not just numeric index numbers?
I have code like
clear;
load eurofx146_c_a_3.mat;
which the file just containing the matrox 'q', then I double click on 'q' in the workspace box and it pops up the spreadsheet view of the data for 'q'.

If you have the Statistic toolbox you can accomplish this with the dataset class.
q = rand(150,10);
names = arrayfun(@(x) sprintf('var%02d',x),1:10,'un',0);
qdat = dataset({q,names{:}});
