icdf

Compute inverse cumulative distribution function values.

Syntax

x=icdf(dist,p,a,b)

Inputs

dist: The distribution name.; Type: string
p: Probability values.; Type: double; Dimension: scalar | vector | matrix
a,b: Distribution parameters.; Type: double | integer; Dimension: scalar

Outputs

x: Values of the distribution random variable.

Example

Vector icdf example with beta distribution.

p = [0.1:0.1:0.9];
a = 2;
b = 3;
icdf('beta',p,a,b)

x = [Matrix] 1 x 9
0.40382 0.48324 0.54145 0.59078 0.63588 0.67941 0.72366 0.77167 0.83036
