Dear,
I am a beginner in programming matlab. In looking around, I have come across a function which looks like:
for j=1: FUE_Num_eachFemto
for i=1:HeNB_Num/4 %Generates Femtocell 1 to 4
x=rand(1)*10; %Generates random variables
y=rand(1)*10; %Generates random variables
FAP(i).location_x=x; %Femtocell Access Point location
end
end
i have problem "FAP(i).location_x=x;" error Structure assignment to non-structure object
thanks!

Marwen - you may need to show more of your code. Even with dummy values for FUE_Num_eachFemto and HeNB_Num, I don't observe any problem with the above code.

Dear, this is my code with values for FUE_Num and HeNB_Num
clc;
clear ;
HeNB_Num=16;
FUE_Num_eachFemto=1; %Number of UE in each unit
Throughput5_total1=1;
Throughput3_total1=1;
for HeNB_Num=4:4:16
%Throughput_total=zeros(4);
clear FAP;
FAP = zeros(1,HeNB_Num/4);
tic;
for j=1: FUE_Num_eachFemto
for i=1:HeNB_Num/4 %Generates Femtocell 1 to 4
x=rand(1)*10; %Generates random variables
y=rand(1)*10; %Generates random variables
FAP(i).location_x=x; %Femtocell Access Point location
FAP(i).location_y=y+(i-1)*10;
thanks!

Error comes in here. FAP(i).location_x=x; FAP is not a structure. It is a non structure and it is already initialized. Check what is FAP. Or try to put different name for instead of FAP. See the below error:
K =rand(10) ;
K(1).location = 10 ;
Structure assignment to non-structure object.
Error in impulse (line 4)
K(1).location = 10 ;
K is a matrix, I tried to associate a filed to it. As K is not a structure, error popped out.

It is not throwing any error in my pc. What version you are using?
