You probably don't need to, or shouldn't need to, but if you insist, you can use the assignin() function. See the help for examples.

you can insert in each function concerned with x y z data the below code
global x y z
you also must run it before, on Matlab Command

I'm sorry, probably I've not explain well my problem.
I'm programming a GUI and I've to export variable from my GUI to matlab workspace or I've to save variables as .mat but I don't know which command can do this...

In the code of the GUI, when you want to export the variables do:
save guioutput
This will save all of the variables in the local workspace to a file named guioutput.mat.
Then from the command line do:
X = load('guioutput');
Now X is a structure with fieldnames the same as the variable names you saved.
If you need to do something more specific, then ask a more specific question...

Thanks, now it's ok, the variable is saved in the pathway where I'm working. If possible I want to save the variable in another pathway and with another name. Can you suggest me something to do this? Thank you very much for your attention.

You can specify where to save the variables and the name of the file. Read this:
doc save
for example:
save('C:\Users\matt fig\Documents\MATLAB3\mvars')
saves all the variables in the local workspace to myvars.mat in the MATLAB3 folder.
