Problem with Subplot "Error using subsindex"

I'm writing a code to plot several subplots in a figure...to simplify it it looks something like this:

h1=subplot(3,2,1); 
plot(x,y)
set(h1,'XTickLabel',{'A','B'},'YTick',[1 2 3],'FontSize',12,'FontWeight','Bold')

This works fine, I finish the different subplots in this figure...

Then I open a second figure and try the same thing:

figure;
h2=subplot(3,2,1); 
plot(x2,y2);
set(h2,'XTickLabel',{'C','D'},'YTick',[4 5 6],'FontSize',12,'FontWeight','Bold')

In this case I get the error:

Error using subsindex
Function 'subsindex' is not defined for values of class 'cell'.

What do I need to do to make it work? why does it work for the first figure (first subplot of first figure to be specific) but it gives me trouble when I try to do the same thing on the second one?

Any help is appreciated...Thanks.

You could get that error if somehow in-between those two, "set" had become a variable, so it thought everything in your () were indices into "set".

Yup...I had a variable called set...I changed it and now it works..Thanks

Thanks for the Q&A.

Alsow worked for me, thanks: I had managed to create a variable named 'axes' which was giving me problems with

sub_axis_h(3) = subplot(2,2,3);     
axes(sub_axis_h(1));   hold on; grid on; xlabel('x'); ylabel('y');
