nanmin

Minimum ignoring NaNs

Syntax

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

Description

m = nanmin(a) is the minimum computed by treating NaNs as missing values. For vectors, nanmin(a) is the smallest non-NaN element in a. For matrices, nanmin(A) is a row vector containing the minimum non-NaN element from each column.

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

m = nanmin(a,b) returns the smaller 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
  [nmin,minidx] = nanmin(m)
  nmin =
       3     1     2
  minidx =
       2     1     3
