I created a variable that stores a set of numbers for an arc (a,b). Sc{1,2} = [1,2]; Sc{2,1} = [1,2]; Sc{1,3} = [2]; Sc{3,1} = [2]; Sc{3,4} = [1,2]; Sc{4,3} = [1,2]; Sc{2,4} = [1]; Sc{4,2} = [1];
I would like to implement the following condition:
s{1} = [1,2];
for v = 1:n,
if s{v} is a subset of s{u}
s{v} = intersect( s{u},Sc{u,v});
end;
end;
I dont know how to code 'if s{v} is a subset of s{u}' in matlab. please help I tried the ismember function:
if(ismember(scenarios{v},scenarios {u}))
but it is showing the following error:
Index exceeds matrix dimensions

That error could arise if either u or v exceeded length(s) . You have not shown us how u is being controlled, and have not shown us the relationship between "n" and length(s) .

At the MATLAB command line give the command
dbstop if error
then run your program. When it stops with the error message, examine the values of u, and v, and size(scenarios) . Also give the command
which ismember
just in case "ismember" got overwritten as a function.
