sorry there was a minor mistake in the program
http://www.mathworks.de/matlabcentral/newsreader/view_thread/164290
This thread describes how to store a solid UNIT circle numerically.
In
the 2nd post of it, he gives the following program
%%%%%%%%%%%%%
clc;
clear all;
nPixels = 101;
radius = 1;
xMin = -radius;
xMax = +radius;
[x,y] = meshgrid(linspace(xMin,xMax,nPixels));
unitCircle = sqrt(x.^2+y.^2) <= radius;
imagesc(unitCircle);axis square;
%%%%%%%%%%%%%
my question is why number of pixels are taken as 101?
If I take it as 501, I thought that circle should completely lie in
the rectangle(and not touch the rectangle, since circle would remain
unit circle, but size of rectangle will increase by 400 pixels)this
doesn't happen , so
why the no. of pixels are 101 and can I take it as some other value
and at the same time keep the circle as a unit circle?
Thank You.
