Smart way of adding paths

For those using multiple PCs, it is necessary to use a smart way of adding paths. How is it possible to add paths like:

a='c:\folder1\'% PC1
b='d:\folder2\'% PC2
c='folder3\'
if PC1
    addpath concatenate(a,c)
else
    addpath concatenate(b,c)
end

so that when using PC1, addpath 'c:\folder1\folder3\'.

Use fullfile.

a='c:\folder1\'% PC1

a = 'c:\folder1\'

b='d:\folder2\'% PC2

b = 'd:\folder2\'

c='folder3\'

c = 'folder3\'

P = fullfile(a, c)

P = 'c:\folder1\/folder3\'

Note that the MATLAB that MATLAB Answers uses to run code in answers is on Linux, so fullfile will add the appropriate

filesep

ans = '/'

between the two parts of the path. If you ran this on Windows the / character would not be present in P.
