Description
            This toolbox is meanly ported from the nan-toolbox for matlab/octave.

Comparison of thrownan and nan_toolbox
======================================
Performance:

size 5000 x 10: sumskipnan: 0.001 sec, sum(thrownan()) 0.002 sec
size 5000 x 50: sumskipnan: 0.005 sec, sum(thrownan()) 0.014 sec
size 5000 x 100: sumskipnan: 0.010 sec, sum(thrownan()) 0.025 sec
size 5000 x 150: sumskipnan: 0.015 sec, sum(thrownan()) 0.039 sec
size 5000 x 200: sumskipnan: 0.018 sec, sum(thrownan()) 0.051 sec

sumskipnan is 2.8 times faster then sum(thrownan()).

The second disadvantage of thrownan is, that a matrix is transformed into a
vector:

-->size(d)
 ans  =
 
    5000.    200.  
 
-->size(thrownan(d))
 ans  =
 
    1000000.    1.

Comment from Petter Wingren -- November 20, 2011, 01:42:24 PM    
I havent been able to install the nan-toolbox on my laptop (64bit linux):

System:

Clevo Stylenote M720T
Intel(R) Core(TM)2 Duo CPU P9500 @ 2.53GHz
Ubuntu 11.10

Installed from Atoms:

>NaN  Toolbox - (1.2.1)
>	Set ieee(2) to allow 0/0
>	Load macros
>	Load gateways
>atomsLoad: An error occurred while loading 'nan-1.2.1-1':
>	Undefined variable: win64

Doesnt work.

Installing nan-toolbox from source on top:

>-->exec('/home/petter/Downloads/Tools/scilab/NaN/builder.sce')
 
 
 
>-->mode(-1);
>Building macros...
>-- Creation of [nanlib] (Macros) --
>Building gateway...
>Generating loader_gateway.sce...
>Generating cleaner_gateway.sce...
>Building help...

>Building the master document:
>	/home/petter/Downloads/Tools/scilab/NaN/help/en_US/

>Building the manual file [javaHelp] in
/home/petter/Downloads/Tools/scilab/NaN/help/en_US>/.
>Total files without example: 66
>Total generated html files: 125
>Generating loader.sce...
>Generating cleaner.sce...

Tried to check if it was installed correctly on all of my above attempts by doing the
following: 
>-->nan_corrcoef
>  !--error 4 
>Undefined variable: nan_corrcoef

removing from Atoms and instaling from source:

>-->exec('/home/petter/Downloads/Tools/scilab/NaN/builder.sce')
 
 
 
>-->mode(-1);
>Building macros...
>-- Creation of [nanlib] (Macros) --
>Building gateway...

Still doesnt work. Any help appreciated.
