fpdf (Statistics Toolbox)

F probability density function (pdf)

Syntax

```
Y = fpdf(X,V1,V2)
```

Description

Y = fpdf(X,V1,V2) computes the F pdf at each of the values in X using the corresponding parameters in V1 and V2. Vector or matrix inputs for X, V1, and V2 must all be the same size. A scalar input is expanded to a constant matrix with the same dimensions as the other inputs. The parameters in V1 and V2 must all be positive integers, and the values in X must lie on the interval [0 ).

The probability density function for the F distribution is

Examples

y = fpdf(1:6,2,2)
y =
    0.2500    0.1111    0.0625    0.0400    0.0278    0.0204
z = fpdf(3,5:10,5:10)
z =
      0.0689    0.0659    0.0620    0.0577    0.0532    0.0487
