nanmax

Maximum ignoring NaNs

Syntax

• m = nanmax(a)
  [m,ndx] = nanmax(a)
  m = nanmax(a,b)
  

Description

m = nanmax(a) returns the maximum with NaNs treated as missing. For vectors, nanmax(a) is the largest non-NaN element in a. For matrices, nanmax(A) is a row vector containing the maximum non-NaN element from each column.

[m,ndx] = nanmax(a) also returns the indices of the maximum values in vector ndx.

m = nanmax(a,b) returns the larger of a or b, which must match in size.

Example

• m = magic(3);
  m([1 6 8]) = [NaN NaN NaN]
  m =
     NaN     1     6
       3     5   NaN
       4   NaN     2
  [nmax,maxidx] = nanmax(m)
  nmax =
       4     5     6
  maxidx =
       3     2     1
