./opale/m2d

• * shear transform in the class AffineTransform2D
• * Bézier Curves
• * B-Splines curves & NURBS
• * Code in Pen2D Logo's rendering functions (such as av,re,td,tg,mv, ...)
• * no translation available until I understand the french version !!!!
• * Scale of the dot clouds
• * cloud dots interpolation
• * Isocurves (f(x,y) = cte ) rendering
• * To code y=a*exp(bx); y=a * x^b; y = a + b ln(x) curves.
• * Display the coordinate systems
• * Display the objects when they ares selected or highlighted
• * Fractal objects generate by a pattern and plane's transformations
• * Create pattern classes (points, triangles, squares, diamants,...) to accelerate the rendering process of functions and dot clouds instead of writing if...then...else statements in the draw method.
• * Optimize in the parser, functions (cartesian, polar or parametric) values computation in order to compute all the values' table at once.

./opale/ode

• * Implement methods from the Runge Kutta family
• * Implement multi-stage methods (Adams...)
• * Try to implement methods with adaptative stages in order to verify if such an operation is possible
• * Implement the management of first degree with constant coefficient linear scalar equations in the kernel: homogenous -> correct resolution; non homogenous -> adapted numerical methods
• * Implement the management of second degree with constant coefficient linear scalar differencial equations : homogenous -> correct ; non homogenous -> adapted methods such as Newmark
• * When the matrix are operational (especially the algorythm of Jacobi's diagonalisation, iterated powers...), we should think about the implementation of degree one and degree two linear differencial systems

./opale/tools

• * RFile : code a method for loading the entire file in a String.

./opale/mathtools

• * Implement sorting out methods for doubles.
• * Should we code an Comparable interface to be able to sort everything ???
• * Add to the parser the possibility to parse boolean expression
• * Classes for the resolution of non linear equations such as f(x) = 0
• * Maybe to conceive a functions' algebra ???
• * Code Fourier Transformations
• * Code the FVect and FArray classes which correspond respectively to
• the DVect and DArray classes with a single precision.
• * Classe Polynomial :
• To code an method which will calculate the derived polynomial.
• To code an equals method which use an epsilon to compare coefficients.
• To sum up the constructors' code.

./opale/matrix

• *) The Crout's solver is implemented without pivot which creates instability. It has to be coded by a research of the pivot. This is not simple.
• *) Coder Gradient conjugue pour SymMatrix -+--comrend pas,what the fuuck?
• *) Code SSOR solver for the Matrix's class
• *) Code a Gauss's method directly for the Matrix's class (see Jean Michel's work)
• *) Code a Gauss's method directly for the BandMatrix's class
• *) Code a symetrical band matrix's class
• *) Then, "puis faire matrice more, matrice profil -----> comprends rien de rien
