weibstat (Statistics Toolbox)

Mean and variance for the Weibull distribution

Syntax

```
[M,V] = weibstat(A,B)
```

Description

[M,V] = weibstat(A,B) returns the mean and variance for the Weibull distribution with parameters specified by A and 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 Weibull distribution with parameters a and b is

and the variance is

Examples

[m,v] = weibstat(1:4,1:4)
m =
    1.0000    0.6267    0.6192    0.6409
v =
    1.0000    0.1073    0.0506    0.0323
weibstat(0.5,0.7)
ans =
    3.4073
