This repository contains the material created for and during the lecture Numerical Methods for Mathematical Finance.
In addition it contains code used in the exercise, e.g. interfaces which are to be implemented.
The lecture is held regularly with a varying selection of topics. The repository evolves and improves. If you like to have the version associated with a specific year you can switch to the corresponding git branch. The main branch should be up to date with the latest version of the lecture.
In the following an incomplete list of code used in the different chapters of the lecture.
See the package info.quantlab.numericalmethods.lecture.computerarithmetics
IntegerArithmeticExperiment- Elementary things related to integer arithmetic: Integer is an equivalence class.FloatingPointNumbersExperiment- Elementary things related to floating point numbers: Understanding their representation.FloatingPointArithmeticExperiment- Elementary things related to rounding.QuadraticEquationExperiment- An example for loss of significance: solving a quadratic equation.SummationExperiment- An example for loss of significance: summation.
We provide small coding assignments related to the lecture. The task is described in the README.md of the corresponding repository. Each repository contains a Maven project including unit test that will perform an "Autograding" of the assignment.

The graph from the motivation session is generated by the class RunningAverageOfIndicator
net.finmath.lecture.numericalmethods.montecarlo.RunningAverageOfIndicator
An example plotting 2D samples from 1D sequence:

In the session on Monte-Carlo integration a one-dimensional integrator is implemented, using the a) Monte-Carlo integration and b) the Simpson's rule.
The implementation can be found in the package
info.quantlab.numericalmethods.lecture.montecarlo.integration1d
The integrators are then tested in a unit test (so this time, there is no "Experiment" with a main() method). The tests can be found in src/test/java in the package
info.quantlab.numericalmethods.lecture.montecarlo.integration1d
The code for the example at the end of the section can be found in the finmath-experiments repository at https://github.com/finmath/finmath-experiments in the class MonteCarloIntegrationExperiment in the package net.finmath.experiments.montecarlo.
The code of the excursus on Java streams can be found in
info.quantlab.numericalmethods.lecture.streams.JavaStreamsExperiments
The interfaces related to the coding assignments for implementing a general integrator are in the package
info.quantlab.numericalmethods.lecture.montecarlo.integration
