# nanmin

min (ignoring Nan's)

### Syntax

[m,index]=nanmin(x)
[m,index]=nanmin(x,'r')
[m,index]=nanmin(x,'c')

### Arguments

x

real or complex vector or matrix

### Description

This function gives for a real or a numerical matrix x his largest element m (but ignoring the NANs).

For x, a numerical vector or matrix, m=nanmin(x) returns in scalar m the largest element of x (ignoring the NANs). The form [m,index] =nanmin(x,orient) gives in addition of the value of the largest element of x (ignoring the NANs) in scalar m, the index of this element in x, as a 2-vector.

m=nanmin(x,'r') gives in the 1xsize(x,2) matrix m the largest elements (ignoring the NANs) of each column of x. If the form [m,index]=nanmin(x,'r') is used, the elements of the 1xsize(x,2) matrix index are the indexes of the largest elements (ignoring the NANs) of each column of x in the corresponding column.

m=nanmin(x,'c') gives in the size(x,2)x1 matrix m the largest elements (ignoring the NANs) of each row of x. If the form [m,index]=nanmin(x,'c') is used, the elements of the size(x,2)x1 matrix index are the indexes of the largest elements (ignoring the NANs) of each row of x in the corresponding row.

In Labostat, NAN values stand for missing values in tables.

### Examples

x=[0.2113249 %nan 0.6653811;0.7560439 0.3303271 0.6283918]
m=nanmin(x)
m=nanmin(x,'r')
