Hello,

I hope this will help:

%let us take circle of unit radius

R = 1;

t = linspace(0,2*pi,100);

x = R*sin(t);

y = R*cos(t);

%now create uniform mesh over square with some given cell size cs

cs = 0.01;

xm = linspace(-1,1,2/cs);

ym = linspace(-1,1,2/cs);

[X,Y] = meshgrid(xm,ym);

%check for points inside the circle

inside = (X.^2+Y.^2

Try this

@ gonzalo , @ Piotr ptat Thank You..

@ Piotr Ptak Sir, let me work on it and hope you don't mind if i get you back when i have some doubts in adapting this code to my application..

@ Piotr Ptak,

Sir, this code is written to find out the distance with which a television signal can propagate with attenuation

The N value that you use with linspace N (r1) is too large.

LINSPACE(X1, X2, N) generates N points between X1 and X2.

You must reduce the resolution of your analysis using a value N between 0 and 5000 depending of your RAM. If you use higher values you will generate a very large matrix with meshgrid and your computer will not be able to deal with.

[X,Y] = MESHGRID(x,y) transforms the domain specified by vectors

x and y into arrays X and Y

@Gonzalo González-Nuevo González

Thanx Sir... I am able to rectify it..

Hi All,

In this program I have to find the power of the signal at any instant [X(inside),Y(inside)]

How can I find it out?

clc;

clear all;

close all;

c=300000000;%speed of light

R_free_space = 1:1000:80000;%distance till 80 kms

f1=350;%frequency of a TV tower

lp_freespace1 =((4*pi*R_free_space*f1*10^6)/c).^2;%free space pathloss

temp1 = 20*log10(10^6)-20*log10(lp_freespace1);

r1=R_free_space(min(find(temp1

This is quite similar to my problem. I would like to split irregular objects in to three smaller region in order to obtain area of each region. Any suggestions?.
