I want to apply Beta distribution to the data but I cnt get any reasonable answer from matlab documentation. I tried fitdist but it didn't work. neither distributionfitter app help in these distributions. can anybody explain me this?

What kind of distribution you want? Gaussian, normal, lognormal?

I want to apply beta distribution. I have taken this example from a book'Simulation with arena' in which they used input analyzer and got the answer for square error for beta distribution. however Matlab say the values must be in interval [o,1]

These are not integers anyway.
But what stops you from normalizing them so they lie in [0,1]?
xmin = min(x);
xmax = max(x);
xhat = (x - xmin)/(xmax - xmin);
[PHAT, PCI] = betafit(xhat)
PHAT =
0.15292 0.39984
PCI =
0.14753 0.35227
0.1585 0.45383
So a beta distribution that lives on [xmin,xmax].
