I have equation having variable A(i) and B(j) where i and j where i varies from 1 to 5 and j varies from 1 to 3. How can I plot this equation by using one value of let say j against all values of i and same for other values of j ?

x = 2^A(i)-2^B(j);

[A,B]=meshgrid(1:5,1:3)
x=2.^A-2.^B

plot either as a surface,

surf(A,B,x)

or in 2D,

plot(x)
