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.
