Hi again
I just reread your mail and I just have a question.

Citat Pol <blenderman at wanadoo dot be>:

> endfor
You can just type
a(1:200) = -inf;
I guess it's faster

I z supposed to a vector or a matrix. If I just cut paste this code z becomes a
matrix due to the linebreak. If z should be a vector you should use an ellipsis
(this is ...). I can get your code to run by adding the ellipsis and
transposing a.

Hope this helps
