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
