Error: Name is nonexistent or not a directory

Wen i type in following code

>>utilpath = fullfile(matlabroot, 'toolbox', 'imaq', 'imaqdemos', ... 'html', 'applications', 'laserTracking'); >> addpath(utilpath);

This is what i get. Warning: Name is nonexistent or not a directory: C:\Program Files\MATLAB\R2007b\toolbox\imaq\imaqdemos\html\applications\laserTracking. > In path at 110 In addpath at 89

how can i go about it?

The path in my (R2010b) installation is:

C:\Program Files\MATLAB\R2010b\toolbox\imaq\imaqdemos\html\laserTracking

Maybe your directory "applications" is wrong?

Andreas i don't think its wrong i was trying out the laser tracking demo in the image acquisition toolbox and thats the exact directory given in there. could it be that i need to get the latest version of matlab? Because i can see that we have different versions.

[Andreas Goser]

So if you can confirm e.g. in the Windows Explorer that this directory is existing, it should be fine. At least for this reason, you do not need to upgrade.

Before I add suggestions, I also like to ask why do you try doing this at all? Just to run a demo? That should not be necessary.

Are you able to add the path interactively (menu File -> Set Path)?

i used the directory without the applications bit and it worked. Thanks Andreas

I dont have an applications directory either, try:

isdir ( utilpath )

to check if matlab recognises it as a directory
