MATLAB: Tick label problems in Matlab 2015a

2015a problemsMATLABticklabel

I tried the following command in Matlab 2013a and Matlab 2014a to remove the tick labels:

plot(1:10, 1);
set(gca,'YTickLabel',[]);

This works perfectly. In Matlab 2015a, I get the following error:

Error using set
Conversion to double from struct is not possible.

Is this a bug or am I doing something wrong?

Most likely, you've created a variable called gca that is a structure and shadowing the gca function.

which gca

will tell you for sure

ax = gca;
get(ax.XAxis, 'MinorTickValues')

For R2014b and later, following also work

ax = gca;
ax.XAxis.MinorTickValues

k = rand(5,1) ; 
plot(k)
xt={'one' ; 'two' ; 'three' ; 'four' ; 'five'} ; 
set(gca,'xtick',1:5); 
set(gca,'xticklabel',xt);
