geomean (Statistics Toolbox)

Geometric mean of a sample

Syntax

```
m = geomean(X)
```

Description

geomean calculates the geometric mean of a sample. For vectors, geomean(x) is the geometric mean of the elements in x. For matrices, geomean(X) is a row vector containing the geometric means of each column.

The geometric mean is

Examples

The sample average is greater than or equal to the geometric mean.

x = exprnd(1,10,6);
geometric = geomean(x)
geometric =
    0.7466    0.6061    0.6038    0.2569    0.7539    0.3478
average = mean(x)
average =
    1.3509    1.1583    0.9741    0.5319    1.0088    0.8122
