I imported a txt file which gave me two columns. Well the top left number needs to be give a label/name(need to display and label it). How would I go about doing this? I have only had matlab for about 3 days. I have gained a slight grasp, but not even close to using it effectively obviously.

Thanks in advance.

There is no way to label or name a number in MATLAB. MATLAB numeric arrays are purely numeric.

Perhaps you are looking for MATLAB's dataset objects?

Or perhaps you are looking to display the numbers as text in the command window, with a header line (or header column) ?

Or perhaps you are looking to make a table in a graphics window, such as with uitable()?

Or perhaps you are wanting to generate an HTML table from the numbers and view it in a browser?

Here, try this:

m = [2342 8768 2654 0796 9703 1727];

for k = 1 : numel(m) if k == 1 fprintf('%d <=== Look there is 2342, and this is its label!\n', m(1)); else fprintf('%d\n', m(k)); end end

In the command window:

2342 <=== Look there is 2342, and this is its label! 2654 9703 8768 796 1727

This code also seems rather effective:

rectangle('Position', [.1 .1 5 3]); axis equal; patch([.1 5.1 5.1 .1], [2 2 3.1 3.1], [.3 .5 .6]); text(0.9, 2.5, 'Hello, my name is', 'FontSize', 30); text(1.8, 1.1, '2342', 'FontSize', 50, 'Color', 'b'); axis off;

See my edit where I added the label code at the end. It should be clear that that is a label.
