# Function mean
|
||
|
|
|
||
|
|
Compute the mean value of matrix or a list with values.
|
||
|
|
In case of a multi dimensional array, the mean of the flattened array
|
||
|
|
will be calculated. When `dim` is provided, the maximum over the selected
|
||
|
|
dimension will be calculated. Parameter `dim` is zero-based.
