statistics: p = unifcdf (x, a, b)
statistics: p = unifcdf (x, a, b, "upper")

Continuous uniform cumulative distribution function (CDF).

For each element of x, compute the cumulative distribution function (CDF) of the continuous uniform distribution with parameters a and b, which define the lower and upper bounds of the interval [a, b]. The size of p is the common size of x, a, and b. A scalar input functions as a constant matrix of the same size as the other inputs.

[…] = unifcdf (x, a, b, "upper") computes the upper tail probability of the continuous uniform distribution with parameters a, and b, at the values in x.
