Dimension: scalar | vector | matrix
dim
Dimension along which the mean is calculated.
Type: double | integer
Dimension: scalar

R
Calculated mean

## Example

Simple mean example

mean([1,4,3;6,2,3;1,29, 9])
R = [ 2.6667 11.667 5 ]

## Example

Mean example with dim

mean([1,4,3;6,2,3;1,29, 9], 2)
R = [ 2.6667 ; 3.6667 ; 13 ]
