Is that possible to assemble several options and pass to the plot function in matlab

Question

I am using matlab to plot several figures and hope these figure use the same plot options. To be more specific, it looks something like this.

N = 20;
Fs = 20         


        

Answer 1

A very clean alternative approach would be to keep the plot command as simple as possible and manipulate the handles afterwards.

opts = {'Color','red','MarkerFaceColor', 'b', 'LineWidth',3};

h(1) = plot(t, x);
grid on;
subplot(312);
h(2) = plot(t, y);
grid on;
subplot(313);
h(3) = plot(t, z);
grid on;

arrayfun(@(x) set(x,opts{:}),h)

The advantage over the indeed neat approach by Nemesis is, that in case you have multiple sets of properties, like:

opts.slimRed = {'Color','red','MarkerFaceColor', 'b', 'LineWidth',1};
opts.fatBlue = {'Color','blue','MarkerFaceColor', 'b', 'LineWidth',5};

and you want to exchange them, you just need to modify one variable

arrayfun(@(x) set(x,opts.fatBlue{:}),h)

to change the appearance of a whole set of handles h.
