Detailed Description

template<typename EigenType_>
struct Tomographer::MAT::EigenPosSemidefMatrixWithSqrt< EigenType_ >::Params

Parameters to read the positive semidefinite matrix.

The main parameter is the tolerance. The tolerance is the minimal acceptable eigenvalue of the returned matrix (in any case must be positive).

The tolerance defaults to Eigen's tolerance, typically 1e-12 for double type.

Internally, we use the Tomographer::MathTools::forcePosSemiDef() family of utilities (preserving the total trace of the matrix). This means that the minimal eigenvalue of the returned matrix will be the tolerance.
