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.
