nanmean

Mean ignoring NaNs

Syntax

• y = nanmean(X)
  

Description

y = nanmean(X) is the average computed by treating NaNs as missing values.

For vectors, nanmean(x) is the mean of the non-NaN elements of x. For matrices, nanmean(X) is a row vector containing the mean of the non-NaN elements in each column.

Example

• m = magic(3);
  m([1 6 8]) = [NaN NaN NaN]
  m =
     NaN     1     6
       3     5   NaN
       4   NaN     2
  nmean = nanmean(m)
  nmean =
      3.5000    3.0000    4.0000
