Fill area of 2dcircle with cross line

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')

thnaku for your kind reply. But i need code for fill the circle with line ,like this

[Awais Saeed]

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')
