### Synopsis

- vals = means(x)

#### Inputs

**x**= matrix (column vector) in which the sample data is stored.

#### Outputs

The return value is a structure with fields:

**amean**= arithmetic mean.

**na**= number of obs used in amean calculation.

**hmean**= harmonic mean.

**nh**= number of obs used in hmean calculation.

**gmean**= geometric mean.

**ng**= number of obs used in gmean calculation.

### Examples

mns = means(x);
