a = 27;
c = 11;
m = 54;
x(1)=2;
for i=2:25
x(i) = (mod(a * x(i-1)+c ,m))
end
here i want to skip the first value x(1)=2 to print in each iteration.
so please guide me how can i skip this value in output.

R(i) = x(i)/m;
if x(i) == x(1)
fprintf('%.2f\n',i-1)
break
end
end
x(2:end)
this is problem i ihave an another condition but it not fulfil by your code.

i want to skip the x=2 in each iteration.
and from my code i received output after each iteration that is too long.so i need a single array output please suggest me.

I don't understand what you are saying. Please explain more. What do you want your output to be?

i want to skip first element from each output after each iteration.and follow the loop with if condition and print a single output for x(i) and R(i).now i think you may understand my problem.

Show me what you want for your output (i=2:4)

AMENDED:
Probably simplest is just
a = 27;
c = 11;
m = 54;
x(1)=2;
for i=2:25
x(i) = (mod(a * x(i-1)+c ,m));
end
x=x(2:end);
maybe? Just guessing; we can't tell what it is that you really want, unfortunately.

What "if" is that??? No if's and's or but's in the question...just the wish to not display the "2" at the begining of each x vector.
The only If is that if we can't understand the question/desired output clearly we can't solve the problem.
Show explicitly what the specific output expected should be.
