example:

A.b=3;

A.c=4;

A.d=6;

save("vv",'-struct','A');

A.d=7;

save("vv",'-struct','A','d'); %%don run correctly

%i dont' want resave A.b A.c ..i want only resave A.d

For the sake of other folks -- like me! -- who didn't realize this, the syntax

save("vv","-struct","A")

saves all the fields of the structure A as individual variables.

So, the question is whether one can just "append" d to the file, even though A.b and A.c may have changed.

here is correct..

but i don't want to add a field 'd' ..i want ro modified on file field 'd' (modifies on file)

I believe that

save('vv','-struct','A','d','-append')

will do what you want
