Saving Workplace variables to .mat files

Hey all, recently I meet the following problem:

Suppose I created a cell named descr like: - descr = cell(1,6);

and after assigning value to each descr{i}, I save it into a file, - save('file.mat', 'descr');

later when I load the file that I just saved, - newdescr = load('file.mat', 'descr'), and update the value of each cell element, - newdescr.descr{i} = newValue;

Then I wish to save the updated cell into the previous file, - save('file.mat', 'newdescr.descr'),

Now the compiler tells me that 'newdescr.descr' is not a valid variable name;

So how do I handle this?

Copy the field to anew variable:

descr = cell(1,6);
descr(:) = {1};
save('file.mat', 'descr');
data = load('file.mat', 'descr');
newdescr = data.descr;
newdescr(:) = {2};
save('file.mat', 'newdescr');

Or use SAVE with the -struct flag.

What you probably want is

save('file.mat', '-struct', 'newdescr');

@Walter: You've been faster. It would be helpful to display a flag, e.g. updated each minute, like: "Walter R. has started to create an answer 3 minutes ago." Then I can stop the fight with the horrible input interface and wait if your answer is as useful as usual.

Heh ;-)

20 hours ago... Let's see... I think it was starting the laundry that delayed me.
