Hello, i want to make bigger all the text in a figure ( title, xlabel, axis,....), so i wrote this line of code in the beginning of the script: set(0,'defaulttextfontsize',30) but it doesn't change anything at all. Could you help me please, how can i change the font size? thank you

I use findall to change the font size for all text in a single figure:
set(findall(gcf,'-property','FontSize'),'FontSize',12)

The correct property name is 'DefaultAxesFontSize', as written above you will get an error. Otherwise this does work.
DefaultAxesFontSize is a better programming practice, but when you use set() the property names are not case sensitive.
set(0,'defaultaxisfontsize',30) or set(0, 'DefaultAxesFontSize', 30) only works for axes text created after the call to set(); it does not change the size for any existing text object, which the findall() version does change.
Works perfectly @onewhaleid. Thanks! +1
