Fredrik,
In the standard formulation of the TSP, the optimal solution can start at any city. If you want to force the solution to start at a specific city, you can manipulate the output as follows:

Supposing that you have requested "optRoute" as an output and that you want the solution to start at the first city, you can type the following into the Command Window:

>> index = find(optRoute == 1);
>> finalRoute = optRoute([index:end 1:index-1])

Newmat, that is because the code is a function. The stuff that happens inside is essentially a black box as far as the stuff outside is concerned. Certain variables are passed as output if you request them (see examples) but if you really need the internal variables, I suggest adding a line at the end of the function that saves the variables to a .mat file. [i.e. add the line: "save('TSPvariables.mat')" without the quotes after the last line of code in the function]

Fredrik, the "showResult" flag does precisely that.

Thanks a lot Joseph, I have also managed to implement your script with some modifications in simulink, where I get a set of waypoints as input =)
