nansum

Sum ignoring NaNs

Syntax

• y = nansum(X)
  

Description

y = nansum(X) is the sum computed by treating NaNs as missing values.

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

Example

• m = magic(3);
  m([1 6 8]) = [NaN NaN NaN]
  m =
     NaN     1     6
       3     5   NaN
       4   NaN     2
  nsum = nansum(m)
  nsum =
       7     6     8
