How to transform the below quadrant plot in to a semicircle plot?

[Azzi Abdelmalek]

What do you mean by transform? Maybe you just want to create a new figure.

fill([-1 1 1 -1 ],[0 0 1 1 ],'b')
hold on
w=0:0.1:pi
x=cos(w)
y=sin(w)
plot(x,y,'w','linewidth',6)
h=area(x,y,'facecolor',[1 0 0])

Acoording to the code given by you, the mirror image is obtained. I want the two quadrant images to be merged to a single image to get a semicircular portion.
