用这个MATLAB代码生成十字阵时，如何把我需要的阵元数，信号频率等信息加进去

Question

如题，求问这个代码中还能加入阵元数，频率，声速等信息吗？如何添加？

clear all

N = 19;
% M = 10;

[ux,uy] = meshgrid(-1:1/100:1);
psix = pi*ux;
psiy = pi*uy;

Beam1 = sinc(1/pi*N*psix/2)./sinc(1/pi*psix/2);
Beam2= sinc(1/pi*N*psiy/2)./sinc(1/pi*psiy/2);
Beam=Beam1+Beam2;
Beam = abs(Beam)/max(max(abs(Beam)));

theta_x=uy*90;
fai_x=ux*180;
mesh(fai_x,theta_x,Beam);
xlabel('x','Fontsize',12);
ylabel('y','Fontsize',12);
zlabel('波束图','Fontsize',12);
title('Response of planar array, N=M=10, dx=dy=\lambda/2, uniform weight')

谢谢各位大佬
