Continuous uniform inverse cumulative distribution function
X = unifinv(P,A,B)
X = unifinv(P,A,B) computes the inverse of the uniform cdf with parameters A and B (the minimum and maximum values, respectively) at the corresponding probabilities in P. P, A, and B can be vectors, matrices, or multidimensional arrays that all have the same size. A scalar input is expanded to a constant array with the same dimensions as the other inputs.
The inverse of the uniform cdf is
The standard uniform distribution has A = 0 and B = 1.
What is the median of the standard uniform distribution?
median_value = unifinv(0.5) median_value = 0.5000
What is the 99th percentile of the uniform distribution between -1 and 1?
percentile = unifinv(0.99,-1,1) percentile = 0.9800
