Writing a variable and reading it elsewhere, how to do that?

After running a programm I have a the end a set of coordinates like Z=[0.4, 0.9; 1.3, 1.4; 2.0, 2.2] I like to use Z in another programm but I do not understand the details of read and write functions. Never done that before...

To save it

save(fullFileName, 'Z');

Then, to load it in your other program

storedStructure = load(fullFileName);
Z = storedStructure.Z;

You can save multiple variables if you want, just list them

save(fullFileName, 'Z', 'myvar', 'someOtherVar');

Thanks, it works. Even simpler with save('Z').

You're giving the filename the same name as your variable, and not specifying any variables at all. So it will save all the variables in scope at the time in your workspace (not just Z) into a file called 'Z.mat'. If you want to do that, that's OK. Personally I like to be more explicit, but as long as you've commented it well, it will work. If we're done, then can you "Accept this Answer".
