I can't run your code without knowing more about a and dam_tot (and other variables). Setting YDir to reverse should flip the order of the numbers on the Y-axis. Can you post a screenshot of what you are seeing, and why it doesn't match what you are trying to get?

Your line
ax.YDir = 'reverse';
is not actually doing what you think it is doing. You should add the following line before it.
ax = gca;
ax.YDir = 'reverse';
or use set()
set(gca, 'YDir', 'reverse');
Your code is not giving an error because it is a valid MATLAB syntax. It creates a new struct object with field YDir.

Without being able to run your code this is just speculation, but it looks like you may be double-flipping your Y-axis tick labels. Two lines of code stick out:
ax.YDir = 'reverse';
set(gca,'YTickLabels',round(flipud((minTorqueRef:torque_range/(resolution-1):maxTorqueRef))));
You have flipud in the call to set the YTickLabels, which may mean you are assigning the wrong tick labels to each tick (essentially assigning them in reverse order). Try commenting out the second line (the one that is setting YTickLabels) and see if it looks like the ticks are in the correct order. If so, remove the flipud.
