Inverse of a specified cumulative distribution function (icdf).
Syntax
X = icdf('name',P,A1,A2,A3)
Description
icdf is a utility routine allowing you to access all the inverse cdfs in the Statistics Toolbox using the name of the distribution as a parameter. icdf('name',P,A1,A2,A3) returns a matrix of critical values, X. 'name' is a string containing the name of the distribution. P is a matrix of probabilities, and A, B, and C are matrices of distribution parameters. Depending on the distribution some of the parameters may not be necessary. The arguments P, A1, A2, and A3 must all be the same size except that scalar arguments function as constant matrices of the common size of the other arguments.Examples
x = icdf('Normal',0.1:0.2:0.9,0,1)
x =
-1.2816 -0.5244 0 0.5244 1.2816
x = icdf('Poisson',0.1:0.2:0.9,1:5)
x =
1 1 3 5 8
