%Calculate the value of e and kp2
p=3
kpi=4
dp = 5
kp2=rand(10); 
e=rand(10);
for i=1:1
    j=1:5
    r=e(j)*dp-kp1*kp2(i)*(p-1)
if r==1
    q1=kp2(i)
    q2=e(j)
    break;
end
end

it doesnot show value of q1 and q2

That's because r is never 1. Assuming your kpi is really kp1, then your code outputs this:

p =
     3
kp1 =
     4
dp =
     5
j =
     1     2     3     4     5
r =
          -2.2984647062648         -1.68125690365354         -2.35894629559188         -6.49583211445794         -3.95680751584107

As you can see, r is never 1 so this line

if r==1

is never true and you never get to the code that would display q1 and q2.

Hi Neet,

I have absolutely no clue what your code is supposed to do, but there are a couple of syntax proplems with what you have copied. Here is a correction with indents and ";" to show the end of a line:

%if true
%Calculate the value of e and kp2 
p = 3; 
kp1 = 4; 
dp = 5; 
kp2 = rand(10);
e = rand(10); 
for i = 1:1 % This loop is redundant 
  for j = 1:5 
      r = e(j) * dp - kp1 * kp2(i) * (p-1);
      if r == 1 
          q1 = kp2(i); 
          q2 = e(j); 
          break; 
      end
  end 
end
%end

This code runs, BUT: 1) The loop for i is redundant 2) r will likely never be equal to 1 since kp2 and e are defined as random numbers Hence, you won't get any values for q1 and q1. You should probably check what this code is supposed to do.

Cheers, Florian

Thanks Florian for your valueable time ...i want to satistisfy the equation e*dp-kp1*kp2*(p-1)=1....my code is not generating r=1..if r is equal to one then the value of e and kp2 is taken..can you suggest other method regarding this...thanking you
