Straight Lines inside Circles

Hi,

          How to draw 10 straight lines horizontally and 10 vertically inside a circlular shape.

Please note that the lines are equally spaced.

Thanks in advance.

Hint:

linspace(-Radius, Radius, 10+2)

and then throw away the first and last of those results.

thanks..i tried to create the grids with ur hint.But failed to draw inside the circle.

I could draw the grid lines with specified X/Y line numbers.But don't know how to restrict the lines inside the circle only.

Radius =150;

xGridLineNumbers=10;

yGridLineNumbers=10;

xmin=-Radius ;

ymin=-Radius ;

xmax=Radius ;

ymax=Radius ;

color=[0 0 0]

x = linspace ( xmin, xmax, xGridLineNumbers);

y = linspace ( ymin, ymax, yGridLineNumbers);

for i = 1 : xGridLineNumbers

      line ( [ x(i), x(i) ], [ ymin, ymax ],'Color', 'color');

    end

for i = 1 : yGridLineNumbers

      line ( [ xmin, xmax ], [ y(i), y(i) ],'Color', 'color');

    end

I got a simple work around!!! function is given below.

xGridLines is the no of X axis grids required.

yGridLines is the no of Y axis grids required.

Radius is the given radius of the circle.

function DrawGridLinesWithRadius(xGridLines,yGridLines,Radius )

horzSample=2*Radius/xGridLines;

vertSample=2*Radius/yGridLines;

for i = 1 : xGridLines-1 % for Horizontal lines

    y=(-Radius)+(horzSample*i);

    xmax=sqrt(Radius^2-(y)^2);

    xmin=-xmax;

    line ([ xmin, xmax ],[ y, y ],'Color',[0 0 0]);

end

for i = 1 : yGridLines-1 % for Vertical lines

    x=(-Radius)+(vertSample*i);

    ymax=sqrt(Radius^2-(x)^2);

    ymin=-ymax;

    line ([ x, x ],[ ymin, ymax ],'Color',[0 0 0]);

end

end
