I plot a single trace in MATLAB with plot(). I'd like to add a right-y axis with a different set of tick marks (scaled linearly). Is this possible?

There are a number of good suggestions on this closely related question, although they deal with a more complicated situation than yours. If you want a super-simple DIY solution, you can try this:
plot(rand(1, 10)); % Plot some random data ylabel(gca, 'scale 1'); % Add a label to the left y axis set(gca, 'Box', 'off'); % Turn off the box surrounding the whole axes axesPosition = get(gca, 'Position'); % Get the current axes position hNewAxes = axes('Position', axesPosition, ... % Place a new axes on top... 'Color', 'none', ... % ... with no background color 'YLim', [0 10], ... % ... and a different scale 'YAxisLocation', 'right', ... % ... located on the right 'XTick', [], ... % ... with no x tick marks 'Box', 'off'); % ... and no surrounding box ylabel(hNewAxes, 'scale 2'); % Add a label to the right y axisAnd here's what you should get:

You may try this submission to MATLAB File Exchange - PLOT2AXES.

Jiro's solution is good (file Exchange function), however, it does not allow to use Matlab's built-in plot functions (bar, scatter, etc.), and you have to use plot2axes instead. Matlab's own help gives the solution to have two axes on any type of plots: ax2 = axes('Position',get(ax1,'Position'),... 'XAxisLocation','top',... 'YAxisLocation','right',... 'Color','none',... 'XColor','k','YColor','k');

Open MATLAB Help with F1 and take a look at the functions below function plot which you mentioned, there you will see plotyy. This is what you probably need.
UPDATE: actually plotyy is NOT the answer to the question as pointed by gnovice.

From matlab 2016 and onwards there is an option to define on what axis one plots:
yyaxis left plots... yyaxis right plots...source: https://se.mathworks.com/help/matlab/ref/yyaxis.html

I was able to do it with the following after plotting the left axis graph:
yyaxis right ylabel('Right axis label') plot(x,y1) % plot your right axis graphHope it helps.
