142. Foreign Language And Math Word Processor Virtu software offers this fully configurable tool that provides insertion of accented letters, Spanish and French punctuation; also Greek letters, wingdings, and math symbols are provided. http://www.virtu-software.com/products/Accenter.asp

Accenter Whether you are typing French accents, Spanish accents, or math symbols, most word processors don't provide the flexibility you need. Adding special characters, commonly used wingdings, or greek letters to your word processing documents can be a nuisance as well. But Accenter works equally well as a Spanish word processor, a French word processor, or a math word processor, because of its configurable setup for inserting special characters. Download Accenter Now! Version: System: Any 32 bit Windows platform Subject: Foreign language/math Grades: Any Description: Word processor with special features for foreign language and math. This word processor is perfect for teachers of mathematics and foreign languages. It's great for anyone who regularly uses obscure symbols in their documents. No longer do you have to use bizarre 'alt key codes' to get the symbols you use most. In fact, Accenter lets you choose the key combinations that are most comfortable for you. What if the key combinations you want to use are not the same as the combinations others want to use? No problem! The customized settings are tied to your Windows user name, so each user can have different settings. How does Accenter work? The user sets up 'symbol groups' (or uses the predefined groups). Each symbol group has its own hotkey combination. For example, the greek alphabet might be activated by pressing [ALT-G]. Within this group, there can be up to 20 symbols, and the keys associated with them. For example, the letter 'a' is associated with the Greek letter 'alpha'. Thus 'alpha' is inserted by pressing [ALT-G], then pressing 'a'.

UBASIC Version 8.74 UBASIC is a BASIC-like environment which is suitable for number theoretic investigations. Version 8 of UBASIC has the high precision real and complex arithmetic (up to 2600 digits) of previous versions, but adds exact rational arithmetic and arithmetic of polynomials with complex, rational, or modulo p coefficients, as well as string handling and limited list handling capabilities. In addition UBASIC has context-sensitive on-line documentation (read ubhelp.doc for information). The file ubhelp.xxx that this uses is ASCII and can be printed for hard copy documentation.

152. Eigenvalues Of Laplacian In The L-shaped Domain By A.L. Skorokhodov and A. Knyazev. http://www-math.cudenver.edu/~aknyazev/software/L/

Andrew Knyazev Eigenvalues of Laplacian in the L-shaped domain In the L-shaped region we consider the eigenvalue problem where is the Laplacian and M is a piece-wise constant function M=1 in and M=M1 in We cover with a mesh, uniform in both directions, with the step h = 1/(N+1). We note, that there are N mesh points on Total number of points in our L-shaped domain is 3N**2 + 2N. In the program , where n can be from 3 up to 15. To make n 16 and larger dimensions of most arrays have to be changed. We use the usual five-point approximation of the Laplacian and a one-point approximation of the operator of multiplication by the function M. That gives us the generalized eigenvalue problem we solve using a preconditioned domain decomposition Lanczos method from A. V. Knyazev and A. L. Skorokhodov, The preconditioned gradient-type iterative methods in a subspace for partial generalized symmetric eigenvalue problem, SIAM J. Numerical Analysis, v. 31, 1226, 1994 ( PDF available The convergence of the method is independent of N and usually every iteration gives one correct digit in the eigenvalue. For the particular problem we solve the cost of one iteration is O(N ln N), and it is required to allocate 8N memory units for components of vectors in the method. To get such low requirements we utilize peculiarities of the problem, for example, we use FFT to solve problems on subdomains. The method can be used for general symmetric eigenproblems as well, but then it is more expensive.
