what is the meaning of set(gca,'Fontsize',16)

Answer 1

[Star Strider]

The gca function returns the handle to the current axes object. The set call sets the 'FontSize' of the associated text objects to 16 points.

Answer 2

[Arif Hoq]

try to plot:

a = linspace(0,10,150);
b = 2*cos(a);
plot(a,b,'Color','r')

[Arif Hoq]

now apply 'gca' in the plot. 'gca' sets the current axes for the current figure which is created before.

a = linspace(0,10,150);
b = 2*cos(a);
plot(a,b,'Color','r')
ax=gca;
ax.YLim = [-4 4]; % in previous figure it was [-2 2]

[Arif Hoq]

'set' sets the property of any object. 'Fontsize' sets the text font to 16.

a = linspace(0,10,150);
b = 2*cos(a);
plot(a,b,'Color','r')

ax=gca;
ax.YLim = [-4 4];
set(gca,'Fontsize',16)

gca
