Hello everybody,
I've the follow problem with 'save' function in Matlab:
I would find a method that permit me to save an entire Matlab workspace but with a name coming from a value of a simulation result variable.
For example:
A = 3000;
save ('A');
In this case I got a file saved with A name and not with it's value 3000 as I would.
How can I solve it?
Thank you in advance.
Best regards.

The filename needs to be a string. You can make a string with a variable value in it by using sprintf and providing the variable;
A = 5000;
save(sprintf('My_A_Value_Is_%d',A),'A');
will save a file called 'My_A_Value_Is_5000.mat' with variable A inside of it.
Do note that you may have to change the type specifier - %d displays integers, %f floating points, etc. Your filesystem may not take kindly to having any characters in the filename.

Knot; I had a typo in the save command (the second argument should have been 'A'), it should now work.

It always helps to read the help. If you do, you will see something like this:
save(filename,variable)
So,
save('A',A) % Make a file named A.mat that has variable A
For more information, type this:
help save

Are you saying that you want to save one file per variable, and that each file will be the name of the single variable stored within? Why on earth would you want to do that, when you can simply store all the variables in one file then load them into a structure with the fieldnames given by the variable names?
Here is how to do it, but I seriously wonder why you would do this:
W = who;
for ii = 1:length(W),save(W{ii},W{ii}),end
