I was reading the depth first search code on matlabtools. But when I tried their code, for
ns = children(adj_mat, u); where adj_mat is an adjacency matrix
matlab gave error message: Undefined function 'children' for input arguments of type 'double'.
Anybody knows what is going on?
Thanks.

How could I? I don't know what matlabtools is. Do you have a URL? At this point all I can say is that you do not have any function or variable called children - same as what the error says.

this is the URL:
http://code.google.com/p/matlabtools/source/browse/trunk/graph/dfs.m?r=121
I typed help children in my matlab,the function children does show up.

Are you talking about this: https://code.google.com/p/matlabtools/ ?
As it says, that code was included in PMTK: https://code.google.com/p/pmtk3/.
And even that code looks like it might not really be supported anymore.

Thanks. I think you are right. But when I typed help children in my matlab (without installing PMTK),the documentation for children does show up.

What do you get from
>> which children
?
children is also a function in the Statistics Toolbox, and it expects a tree as an input.
