[X,Y] = meshgrid(-2:.2:2);lambda=.000000001;z=.000010;R =X.^2;
F = exp((i.*pi.*R)./(lambda.*z));
mesh(imag(F));
l=20e-6;
w=4e-6;
Ts=1e-9;
t1=0:Ts:w;
t0=w+Ts:Ts:l-Ts;
s1=ones(size(t1));
s0=zeros(size(t0));
s=[s1 s0];
N=7; %How many repetitions of the wave
ss=repmat(s,1,N);
t=0:Ts:N*l-Ts;
plot(t,ss)
ss=imresize(F,[21 21]);
az=ss.*F;
plot(t,az)

Tulika - why not include the error message? If I try to run the above code, I observe
Error using plot
Vectors must be the same lengths.
This is because your t is a 1x140000 array of doubles whereas az is a 21x21 array of complex numbers. Since they are of different dimensions, then the error message makes sense.
Step through the code to observe the same, and consider what is happening at each line and whether it makes sense.
