How do I make the default gray figure background into white?

I'd like to change my default factory setting so that all figures I will ever make will appear on a white background, instead of the current default gray background. (I'm talking about the color of the background outside the actual figure).

It is similar to this question, except that I tried the answer to this question and it does not work: http://www.mathworks.com/matlabcentral/answers/96816-how-do-i-change-the-default-background-color-of-all-figure-objects-created-in-matlab

Thanks in advance

Please explain what "it does not work mean", because the shown method works and is the only way to achieve, what you want.

Thanks, what I mean by it doesn't work:

The command does work in the short term. But, once you close the session and reopen it, then the default appears again. I'm using 2012a, so maybe that might be the issue.

Try this:

set(0,'defaultfigurecolor',[.4 .1 .5])
plot(1:9, 'bo-');

Do you get a purple background behind the plot? I do.

To get it to happen and be this color session after session, put the code into your startup.m file.

Thanks, this works but once I restart Matlab the default is gray again.
