Our next meeting will be held in COE 796 aka. Paul Erdos room, on Wednesday 21st of April 2010 from 3:00 PM - 4:00 PM. The speaker is Dr. Michael Stewart. The title of his talk is "Haskell for Mathematical Programming".

Abstract: We will give an informal introduction to the functional programming language Haskell with an emphasis on features that might be of interest to mathematicians. The key points are:
1. Haskell is functional. This means that most functions in Haskell are functions in the ordinary mathematical sense. A function takes an argument and returns a value that depends only on the value of argument; it doesn't manipulate or depend on a mutable hidden state. There is remarkable flexibility in manipulating and combining functions.
2. Haskell is fast and interactive. The main implementation, the Glasgow Haskell Compiler (ghc), has both a compiler and an interpreter. Carefully written compiled code can be close to C in speed. The interpreter allows interactive use like MATLAB.
3. Haskell has a flexible polymorphic type system with type inference. Types are inferred and type errors are caught at compile-time without the need for explicit annotation of types in the code. The polymorphism means that functions can be applied to more than one type. The multiplication operator "*" is as applicable to matrices, or any other suitable user defined type, as it is to integers or floating point numbers.
4. Haskell uses lazy evaluation of functions (by default). It does not compute the value of any function unless the value is needed. This allows the easy definition of conceptually infinite data structures, e.g. the sequence of all primes. Such Haskell code often ends up looking like a straight-forward transcription of mathematical definitions.

Math Club and SwIG Joint Event

The first joint Math Club and SwIG meeting will be held in COE 796 aka. Paul Erdos room, on Wednesday 21st of April 2010 from 4:10 PM - 5:10 PM. The speaker is Dr. Bree Ettinger. The title of her talk is: "Introduction to LaTeX".

Abstract: In this talk, we will describe the use of LaTeX on Windows platform from installation of TeX up to the point when you create your first document. We will show you how to properly install MikTeX on Windows platform and configure WinED. We will also take a look at Sumatra PDF viewer and show how to use Inverse and Direct search on WinED. By the end of this talk everyone should be ready to start making great looking mathematical documents.
