So I have a list of variables, defined in my workspace, and I'm trying to access them each in turn to compare them to a larger matrix A. The eval function calls each variable in turn, stores it under temporary matrix B, then compares it to matrix A, does the necessary calculation, and stores it...
Hi, All:
I have a Windows 7 Pentium system with IE--pretty close to the latest update. My list of favorite Internet sites is pretty large; easily more than 60 items. Sadly, my system has crashed a few times over the last 2-3 years, and I have lost the list each time when reinstalling...
Greetings,
Is there a commonly accepted notation for a list in mathematics, of an identical form to Ʃ for a summation? If so, what is the name of the symbol (that would be used in place of L, below), and how would it be typed in LaTeX?

I think it might be a good idea to create a list of various jobs that have an open door for someone with a physics degree, BS, MS, or PhD. I would like to add slightly unrelated fields as well, since job hunting can be a nightmare.

On our first test there were about 4 different methods. This test there are about 4-5. There are 4 tests in the class. I'd like to get ahead. The pattern seems to be that you first identify the method that needs to be used, then simply preform the method steps. It is that strange of a thing to...
