hi,i m trying to find all possible paths using recursion in matlab. the code for recurssion is as follows:
function[allpaths=findnodes(maxnodes,source,destination,path,marked)
all paths = [];
marked=[marked source];
if (source==destinstion)
allpaths=path;
disp(['path is::'num2str(allpaths)]);
return;
else
for v=1:maxnodes; //for all the neighbours of source node
if ~ismember(v,marked)
path=[path v];
allpaths=[allpaths (findnodes
(maxnodes,v,destination,path,marked))];
index=find(path==v);
path(index)=[];
else
allpaths=[path];
end;
end;
end;
but here the recursion is not working properly.
can anybody help me?

Do not use the term path for a variable, because this shadows a very important Matlab function.
The number of square brackets in the 1st line is unbalanced.
I assume you want "allpaths = [];" instead of "all paths = [];". Spaces do matter in Matlab.
