if x=[0:0.2:2]; and y=[-0.4:0.1:0.2]; and the equation of y=x/(x+r)-1/(1+r) and r is non linear it is many of curves and the values of r is r=0.1, 1, 10, 100 how can i plot it in matlab please help me i am trying many methods but still has a problem

[KALYAN ACHARJYA]

here all are variables x,y,r, what is variant with respect to variables?

[Ashrakat Adel]

r vary with x, y

[KALYAN ACHARJYA]

r values are given r=0.1, 1, 10, 100??

[Ashrakat Adel]

no r in first have a value 1 then in anther curve 10 and third 100

I have answered the question what I have understood, now you can modify the code as per your requirements

Answer 1

[KALYAN ACHARJYA]

Are you looking for this one? Considering y is finding function wrt x and r.

   x=0:0.2:2;
   %y=-0.4:0.1:0.2;
   r=[0.1 1 10 100];
   for i=1:4
   y=x./(x+r(i))-1/(1+r(i));
   plot(x,y);
   hold on;
   end
   legend('r=0.01','r=1','r=10','r=100');
