Hi,
Please guys help me out. I have a problem in solving the iterative equation. i have an equation say 2u-3+ln(u-0.5)+2x=0. For every iteration, say upto 30 iterations, 'x' changes as 0:dx:1, hence for every change of x, i need to find 'u' and store it. I have tried using fzero,inline,solve but could not get the vector 'u'. Can anyone please help me out in writing this code

FZERO should have worked. You should show your coding attempt so we can see what might have gone wrong.

hi, you can solve your equation by many ways , try :
a=solve('2*u-3*log(u-0.5)+2*x','u')
u=subs(a,linspace(0,1,30));
plot(u) % this is the solution
Now you can verify your solution U :
X=linspace(0,1,30);
ZZ=2*u-3*log(u-0.5)+2*X;
