mean

Syntax

m=mean(x)

m=mean(x,dim,opt)

Inputs

x

Data sample.

Type: double

Dimension: vector | matrix

dim

Dimension on which to perform the calculation.

Default: first non-singleton dimension.

Type: integer

Dimension: scalar

opt

The available options are as follows:

'a'

Arithmetic (default).

'g'

Geometric.

Outputs

m

Mean.

Dimension: scalar | matrix

Examples

x=[9.3, 10.6, 11.9, 13.3, 15.1, 18.2];
m=mean(x)

m = 13.0666667

x = [9.3, 4.8; 10.6, 6.6; 11.9, 8.0; 13.3, 9.3; 15.1, 10.6; 18.2, 11.9];
m=mean(x)

m = [Matrix] 1 x 2
13.06667  8.53333

Comments

mean(x) = sum(x) / n
