syms x
f=inline('(x^2)+(54/x)'); % Function
while x3<=b %Conditions
if f(x1)>=f(x2) && f(x2)<=f(x3) %Conditions
disp('minima lies between x1 and x3')
x1=x2; x2=x3; x3=x2+dx; % Modified values of x1 x2 & x3 if above condition is not satisfied.
% from these values it should goto start point until conditions are satisfied

You have not defined dx.
You are not using "x" so "syms x" is not needed.
