How to mark a point on scatter plot obtained using gscatter?

I just obtained a scatter plot using gscatter(x,y), where x and y are both data vectors with size 100. Among these 100 points, a point (x*,y*)=(50,50.5) have some particular meaning and I want to highlight this point with a different point style or color. How could I do it?

Thanks!

Yes you can specify that, see my example (Just for understanding)

x=randi(100,[1,50]);
y=randi(100,[1,50]);
gscatter(x,y);
hold on;
%....................... Group,color,marker,marker size 
gscatter(x(1,25),y(1,25),2,'r','x',[10,15]);

@KALYAN ACHARJYA Hi KALYAN, another question: what does x(1,25),y(1,25) mean?

Specifying particular index points.
