# nanmax

max (ignoring Nan's) **This function is obsolete**,
replaced with max

### Syntax

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

### Arguments

- x
real or complex vector or matrix

### Description

This function is obsolete and will be removed from Scilab 6.1. Please use
`max()` instead. |

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=nanmax(x)`

returns in scalar `m`

the largest
element of `x`

(ignoring the NANs). The form
`[m,index] =nanmax(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=nanmax(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]=nanmax(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=nanmax(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]=nanmax(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=nanmax(x) m=nanmax(x,'r') m=nanmax(x,'c')
