nanmedian

Median ignoring NaNs

Syntax

• y = nanmedian(X)
  

Description

y = nanmedian(X) is the median computed by treating NaNs as missing values.

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

Example

• m = magic(4);
  m([1 6 9 11]) = [NaN NaN NaN NaN]
  m =
     NaN     2   NaN    13
       5   NaN    10     8
       9     7   NaN    12
       4    14    15     1
  nmedian = nanmedian(m)
  nmedian =
      5.0000    7.0000   12.5000   10.0000
