Introduction

This documentation provide the documentation for the following solvers:

• BackgroundErrorCostSolver

• CovarianceVectorMultiplySolver

• GaussianSimulationSolver

They are all based on operations involving covariances matrices. Different methods have been implemented to compute or apply covariances matrices. These methods are described in the documentation of the module:

• CovarianceUtils

Remark

The complete pdf documentation can be obtained using pandoc:
