Hi

I have a very simple/naive question.

I am using a code(written below) to calculate the shortest paths
between two network nodes.

for i = 1: length(path)
fprintf('Path # %d:\n',i);
disp(path{i})
fprintf('dist of path %d is %d\n\n',i,dist(i));
end


I get the paths along with their costs:

Path # 1:
1 2

cost of path 1 is 10

Path # 2:
1 4 5 2

cost of path 2 is 30

After getting the paths and their cost i want to assign Path #1 and
Path #2 to a new variable lets say newp.

for g = 1:2
newp = (Path(g));
end

But i always get the error.

Can anyone please help me.

What error message do you get?

Perhaps you mean:
newp = (path(g));

It appears you are trying to create variable names in a loop. That is
very much recommended against.

well... how can CSSMers be of any help if you don't show the full error stream(?)...

Regardless of the resolution, it is a BADDDD idea to use the
name path for a variable name, as that overshadows the
useful function path.

Try to avoid doing things like this.

As far as you actual problem goes, you cannot assign
a vector to an element of a double array. So learn to
use cell arrays instead for this assignment.
