could anyone help me to measure the distance between base station and users with respect to the following code.

code:

user=[6];
for t = 1:length(user)
        Xmax=1; 
        Ymax=1; 
        radius=2; 
        xsd=ones(1,user(t))*Xmax;
        ysd=ones(1,user(t))*Ymax;
        rrx=radius*sqrt(rand(1,N_UE(t)));
        thetarx=2*pi*rand(1,N_UE(t));
        xrx=xsd+rrx.*cos(thetarx); 
        yrx=ysd+rrx.*sin(thetarx); 
        th = 0:pi/100:2*pi;
        xunit = radius * cos(th) + Xmax;
        yunit = radius * sin(th) + Ymax;
            figure
            plot(xunit, yunit);
            hold on
            plot(ysd,xsd,'r^')
            hold on
            plot(yrx,xrx,'ko')
            hold on

The code executes and gives me the figure.

With respect to the figure i need to measure the distance between all users with respect to the base station.

Could anyone please help me how to measure it.

USe distance formula:

d = sqrt((x2-x1)^2+(y2-y1)^2) ;

[Walter Roberson]

if you have more than one base station use pdist2

What is N_UE(t)

Answer 1

[KSSV]

user=6;
d1 = zeros(user,1) ;
d2 = zeros(user,1) ;
for t = 1:length(user)
    Xmax=1;
    Ymax=1;
    radius=2;
    xsd=ones(1,user(t))*Xmax;
    ysd=ones(1,user(t))*Ymax;
    rrx=radius*sqrt(rand(1,N_UE(t)));
    thetarx=2*pi*rand(1,N_UE(t));
    xrx=xsd+rrx.*cos(thetarx);
    yrx=ysd+rrx.*sin(thetarx);
    th = 0:pi/100:2*pi;
    xunit = radius * cos(th) + Xmax;
    yunit = radius * sin(th) + Ymax;
    figure
    plot(xunit, yunit);
    hold on
    plot(ysd,xsd,'r^')
    hold on
    plot(yrx,xrx,'ko')
    hold on
    d1(t) = sqrt((xunit-xsd)^2+(yunit-ysd)^2) ;
    d2(t) = sqrt((xunit-xrx)^2+(yunit-yrx)^2) ;
end

when i run the code its giving error stating

Error using -

Matrix dimensions must agree.

Error in test1 (line 24)

d1(t) = sqrt((xunit-xsd)^2+(yunit-ysd)^2) ;

Could you please help me on this.

[jaah navi]

I tried with command line d1 = sqrt((xsd-xrx).^2+(ysd-yrx).^2) ;

then the code executes without error.

[KSSV]

It seems the input is a vector......

[jaah navi]

yes.

with respect to the code shown above i am getting the figure without any error.

with respect to the command line it gives the data of d1=size(1,6) where

d1= 0.7036 1.3659 0.4003 1.4788 1.9625 0.8593

But i need to display it in the following manner.

distances(:,:,1) =0.7036

distances(:,:,2) =1.3659

distances(:,:,3) =0.4003

distances(:,:,4) =1.4788

distances(:,:,5) =1.9625

distances(:,:,6) =0.8593

Could you help me to display in the format as desired.

[KSSV]

How it is going to matter? You initilaize it as

d1 = zeros(1,1,user) ;

[jaah navi]

with respect to the code

user=6;

d1 = zeros(user,1) ;

for t = 1:length(user)

Xmax=1;

Ymax=1;

radius=2;

xsd=ones(1,user(t))*Xmax;

ysd=ones(1,user(t))*Ymax;

rrx=radius*sqrt(rand(1,N_UE(t)));

thetarx=2*pi*rand(1,N_UE(t));

xrx=xsd+rrx.*cos(thetarx);

yrx=ysd+rrx.*sin(thetarx);

th = 0:pi/100:2*pi;

xunit = radius * cos(th) + Xmax;

yunit = radius * sin(th) + Ymax;

figure

plot(xunit, yunit);

hold on

plot(ysd,xsd,'r^')

hold on

plot(yrx,xrx,'ko')

hold on

d1 = sqrt((xsd-xrx)^2+(ysd-yrx)^2) ;

end

totally there are 6 users shown in black color as it is stated as 'ko'.

I want to display the users in different colors with respect to distance.

example: user with the first minimum distance with respect to (xsd,ysd) should be in one color,user with the second and third minimum distance with respect to (xsd,ysd) should be in another color,user with the fourth and fifth minimum distance with respect to (xsd,ysd) should be in another color and last user in different color.

Could you please help me on this.

cprintf in the File Exchange .

Could you please elaborate on cfprintf in the File Exchange
