Extractions: Next: Localised discrete Fourier transform Up: Theory Previous: Theory The most straightforward approach to the evaluation of the Laplacian operator applied to a function at every grid point is to approximate the second derivative by finite differences of increasing order of accuracy [ ]. For example, the part of the Laplacian on a grid of orthorhombic symmetry is where is the grid spacing in the -direction, is the order of accuracy and is an even integer, and the weights are even with respect to , i.e. . This equation is exact when is a polynomial of degree less than or equal to . The leading contribution to the error is of order . The full Laplacian operator for a single grid point in three dimensions consists of a sum of terms. In principle, for well behaved functions, the second order form of equation ( ) should converge to the exact Laplacian as . Therefore to increase the accuracy of a calculation one would need to proceed to smaller grid spacings. However, in most cases of interest, this is computationally undesirable and instead, formulae of increasing order are used to improve the accuracy at an affordable cost [ ]. Chelikowsky et al. [

Extractions: So now we have a Leibniz-like rule. We can compute finite differences of polynomials without using subtraction or division! What's more, we can use these formulae to difference algebraic functions defined implicitly by polynomials. For example consider f(x)=1/(1-x). We can rewrite this implicitly, using only addition and multiplication, as Differencing both sides we get We're now ready to apply our operator to types. Instead of functions on the reals we work with functors on the set of types. A good first example container is the functor F(X)=X N for an integer N. This is basically just an array of N elements of type X. We could apply the Leibniz rule repeatedly, but we expect to get the same result as if we'd worked over the reals. So setting f(x)=x

Extractions: Next: Recursion Up: Tools Previous: Induction The method of finite differences can sometimes be used to guess a formula f n ) (but not to prove it). The way I am about to describe it requires that the values of f n ) be given for integer values of n beginning with n =0 (rather than 1). Let's use the example of guessing the formula for the sum of the cubes of the first n positive integers. We calculate a few values: and then arrange them in a row. Then we build a difference table beneath them by subtraction: We continue generating rows by this process until it appears that we get a row of 0's. This does not always happen, but when it does, we can build a polynomial formula for f n ). Using the first entries in each row, multiply the first entry of the first row by 1/0!, the first entry of the second row by n /1!, the first entry of the third row by n n -1)/2!, the first entry of the fourth row by n n n -2)/3!, the first entry of the fifth row by n n n n -3)/4!, etc., and then add the results. (Remember that 0! is defined to be 1.) In our example, we get which simplifies (you try it!) to

Many times we consider only the positive values in the resulting series of numbers. When deriving series in this manner, of note are the 7th and 13th values (either the 7th or 13th overall positive values, or the 7th and 13th from the first number, a). If we would start with 4 numbers, a, b, c, and d, then we would normally need to use a four row table to arrive at the base of the series. Some series (such as the Covenant Numbers) are overdetermined, i.e., though the Torah provides us with 4 initial values in the series, only 3 are needed to find the base (see Covenant Numbers for more).

Extractions: Using a library for matrix algebra What really distinguishes C from standard C is the ability to extend the language by creating classes and collecting these classes into libraries. A library is a collection of classes and routines for one particular purpose. We have already seen this idea when creating the date and classes. However, one should not necessarily always go ahead and create such classes from scratch. It is just as well to use somebody else class, as long as it is correct and well documented and fulfills a particular purpose. Use Newmat as an example matrix class. [reference to www]. Discuss alternatives. Finite Differences We use the case of implicit finite difference calculations to illustrate matrix calculations in action. The method of choice for any engineer given a differential equation to solve is to numerically approximate it using a finite difference scheme, which is to approximate the continous differential equation with a discrete difference equation, and solve this difference equation.
