Hello,

I am seriously new to any kind of programming, so apologies in advance.

I am trying to graph two functions (nullx, nully) where null x is a function of y and null y is a funciton of x.

The graph should be on a typical x-y plane, but I am not getting any plots out of my code. I appreciate any help, and please explain specifically. Thank you!

a = 0.2;
%nullx= -(y-a-a*y)/(-a-a*y);
nully= -(x-a-a*x)/(-a-a*x);
for y = 1:10
    nullx= -(y-a-a*y)/(-a-a*y);
    plot(0:10,nullx);
end

You would benefit by going through MATLAB Onramp.

Ch 3 covers creating vectors and matrices
Ch 6 covers array calculations (eliminating the need to use a for loop)
Ch 9 covers plotting
Ch 13 covers for loops, and more importantly, capturing the result from each loop
