In the code below "rect" for rectangular function is not working. Please give me a way to implement rectangular function in matlab.....
wx=0.1; %rect x half-width (m)
wy=0.05; %rect y half-width (m)
L=2; %side length x&y (m)
M=200; %samples/side length
dx=L/M; %sample interval (m)
x=-L/2:dx:L/2-dx; %x coordinates
y=x; %y coordinates
[X,Y]=meshgrid(x,y); %X and Y grid coords
g=rect(X/(2*wx)).*rect(Y/(2*wy));
