MATLAB: Add labels to columns

Question

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'.

Answer 1

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{:}});
