nanmin (Statistics Toolbox)

Minimum ignoring NaNs

Syntax

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

Description

m = nanmin(a) returns the minimum with NaNs treated as missing. 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
