MATLAB: Customizing xticks yields error: ” Undefined function ‘xticks’ for input arguments of type ‘double’.”

xticksxticks undefined

I am trying to customize the x- and yticks on my plot axes. But even running the basic example provided by Matlab
x = linspace(-10,10,200);
y = cos(x);
plot(x,y)
xticks([-3*pi -2*pi -pi 0 pi 2*pi 3*pi])
xticklabels({'-3\pi','-2\pi','-\pi','0','\pi','2\pi','3\pi'})
yticks([-1 -0.8 -0.2 0 0.2 0.8 1])
(see link https://de.mathworks.com/help/matlab/creating_plots/change-tick-marks-and-tick-labels-of-graph-1.html) will yield the error message cited in the title. Restart did not help. Running R2014b, 64-bit, on an OS X Yosemite Mac.
What is that error due to and how can I solve it?
Thanks a lot for the help!

The xticks function was introduced in R2016b. In earlier releases you must use the code below (this code also works on newer releases).
x = linspace(-10,10,200);
y = cos(x);
plot(x,y)
set(gca,'XTick',[-3*pi -2*pi -pi 0 pi 2*pi 3*pi])
set(gca,'xticklabel',({'-3\pi','-2\pi','-\pi','0','\pi','2\pi','3\pi'}))
set(gca,'YTick',[-1 -0.8 -0.2 0 0.2 0.8 1])
