kstest and hypothesis rejecting

When one does a kstest in matlab and the h=0, what does that mean? The null hypothesis has failed? What about when h=1?

When in doubt, use help()

help kstest
 kstest Single sample Kolmogorov-Smirnov goodness-of-fit hypothesis test.
    H = kstest(X) performs a Kolmogorov-Smirnov (K-S) test to determine if
    a random sample X could have come from a standard normal distribution,
    N(0,1). H indicates the result of the hypothesis test:
       H = 0 => Do not reject the null hypothesis at the 5% significance
       level. 
       H = 1 => Reject the null hypothesis at the 5% significance
       level.

The null hypothesis depends on your inputs. Again, from the documentation using doc(ktest):

Test the null hypothesis that the data comes from a normal distribution with 
a mean of 75 and a standard deviation of 10. Use these parameters to center 
and scale each element of the data vector since, by default, kstest tests for 
a standard normal distribution.

x = (test1-75)/10;
h = kstest(x)
