I have a y axis that spans 0 - 15. I want to place an extra tick mark (labelled with its value) at the minimum value of y (0.018 in one data set, for example).
It is not appropriate for me to use a log scale - the data is well presented, it is just not obvious to the reader that the minimum value is not zero.
Thank you.

set(gca, 'YTick', sort([0.018, get(gca, 'YTick')]));

After setting the YTick, you can pull out the YTick again and format the values and send those to the YTickLabels property.
With R2014b or later you would typically only do that if you had special formatting needs, such as needing one label to look different than the others, or if you wanted to convert each value to its multiple of Pi : for plain formatting issues you would instead set the axes YAxis.TickLabelFormat property.
