Hi,
I need to product two vector as Ta and r1 but I got error (In an assignment A(I) = B, the number of elements in B and I must be the same.). in fact, my goal is make iteration on all body of script. I couldn't understand what is wrong?
my codes is following as:
N=100; a=0; a1=10; a2=5;
alfa=0.5*pi/180;
teta0=ones(1,3); L=ones(1,3); B=L; Ta(:,:)=ones(1,3);
Roc=inf; Rdisk=inf; landa=1.03e-3; k=2*pi/landa;
r1=linspace(a,a1,N); r2=linspace(a,a2,N);
n=[1.45 1.8153 2.4];
for s1=1:size(n)
teta0(s1)=(n(s1)-1)*alfa; L(s1)=0.5*a1./teta0(s1); B(s1)=L(s1);
kernel12=ones(1,N,s1); kernel21=ones(1,N,s1);
H12=ones(1,N,s1); H21=ones(1,N,s1);
Ta(s1)=exp(-1i*2*teta0(s1)*k*r1);
Tdisk=exp(-1i*k*r2.^2/Rdisk);
Ttot=Ta(s1).*Tdisk(1:N);
Toc=exp(-1i*k*r2.^2/Roc);
end

Line 11 should be
Ta(s1)=exp(-1i*2*teta0(s1)*k*r1(s1));
You missed the index s1 in r1 (r1(s1) insteas of r1)

thanks,
I think it is couldn't best idea because the size of r1 is 1*200 and when we use r1(s1) instead of r1 only 3 elements of r1 selected because s1 is a 3 elements vector.
it is my idea and I don't know that it is true.
another problem, that I faced it, is kernel12(:,:,1)=0 and kernel12(:,:,2) has value, what is wrong? whereas it must has value.

This your problem, you should know what are the sizes of your data. What is the expected size of Ta?
