mean (MATLAB Functions)

MATLAB Function Reference

mean

Average or mean value of arrays

Syntax

```
M = mean(A)
M = mean(A,dim)
```

Description

M = mean(A) returns the mean values of the elements along different dimensions of an array.

If A is a vector, mean(A) returns the mean value of A.

If A is a matrix, mean(A) treats the columns of A as vectors, returning a row vector of mean values.

If A is a multidimensional array, mean(A) treats the values along the first non-singleton dimension as vectors, returning an array of mean values.

M = mean(A,dim) returns the mean values for elements along the dimension of A specified by scalar dim. For matrices, mean(A,2) is a column vector containing the mean value of each row.

Examples

A = [1 2 3; 3 3 6; 4 6 8; 4 7 7];
mean(A)
ans =
    3.0000    4.5000    6.0000

mean(A,2) 
ans =
    2.0000
    4.0000
    6.0000
    6.0000
