Continuous uniform mean and variance
[M,V] = unifstat(A,B)
[M,V] = unifstat(A,B) returns the mean of and variance for the continuous uniform distribution using the corresponding lower endpoint (minimum), A and upper endpoint (maximum), B. Vector or matrix inputs for A and B must have the same size, which is also the size of M and V. A scalar input for A or B is expanded to a constant matrix with the same dimensions as the other input.
The mean of the continuous uniform distribution with parameters a and b is (a + b)/2, and the variance is (a – b)2/12.
