below is simple circle code, can anyone tell me how to fill this circle with line pattern.
theta=linspace(0,2*pi,100);
x=cos(theta);
y=sin(theta);
plot(x,y)
axis('equal');
xlabel('x')
ylabel('y')
title('circle of unit radius')

Do not know how to fill with lines, but you can fill the circle as shown below
theta=linspace(0,2*pi,100);
x=cos(theta);
y=sin(theta);
fill(x,y,'g')
axis('equal');
xlabel('x')
ylabel('y')
title('circle of unit radius')

Not exactly the same but somewhat near to the desired output
theta=linspace(0,2*pi,100);
x=cos(theta);
y=sin(theta);
plot(x,y,'black')
for ii = 1:2:length(x)
line([-y(ii),x(ii)],[-x(ii),y(ii)],'Color', 'black','LineWidth',1)
end
axis('equal');
xlabel('x')
ylabel('y')
title('circle of unit radius')
