The equations are given in the attachment. Assume lambda=1. How to implement the given equations in MATLAB?

fn=@(theta,k) exp((0:k-1).' * (2i*pi*d/lambda*sin(theta)));
A=fn(theta,M);
B=fn(theta,N);
y=reshape( A*B.', [],1);

Ran in:
No, the Kronecker product of two vectors is a vector, e.g.,
a=[1;2;3];
b=[4;5];
kron(a,b)
ans = 6×1
4 5 8 10 12 15

I made changes to yours as:
theta=[10 20 30];
M=10;
N=4;
K=3;
lambda=1;
d=0.5;
fn=@(theta,k) exp((0:k-1).' * (2i*pi*d/lambda*sin(theta)));
A=fn(theta,0:M-1);
B=fn(theta,0:N-1);
But now it gives A and B as empty matrices
