For each element of p, compute the quantile (the inverse of the CDF) of the discrete uniform distribution with parameter N, which corresponds to the maximum observable value. unidinv assumes the integer values in the range [1,N] with equal probability. The size of x is the common size of p and N. A scalar input functions as a constant matrix of the same size as the other inputs.

The maximum observable values in N must be positive integers, otherwise NaN is returned.

Warning: The underlying implementation uses the double class and will only be accurate for N < flintmax (2^{53} on IEEE 754 compatible systems).

Further information about the discrete uniform distribution can be found at https://en.wikipedia.org/wiki/Discrete_uniform_distribution

Input arguments must be double or single; integer, logical, and character arrays are rejected. MATLAB accepts a character array and evaluates it at the character codes, which Octave deliberately does not, since a character array is an integer type and integers are refused too.
