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.

Examples

• A = [1 2 4 4; 3 4 6 6; 5 6 8 8; 5 6 8 8];
  mean(A)
  ans =
      3.5000    4.5000    6.5000    6.5000
  
  mean(A,2) 
  ans =
      2.7500
      4.7500
      6.7500
      6.7500
