pm_matrixDet::setMatDetSqrtLog Interface Reference

Return the natural logarithm of the square-root of the determinant of the input positive-definite square matrix. More...

Detailed Description

Return the natural logarithm of the square-root of the determinant of the input positive-definite square matrix.

The positive-definiteness guarantee by the user enables a fast method of computing the determinant of the input positive-definite square matrix via its Cholesky Factorization.
Computing the logarithm of the square-root of the determinant is preferrable for high rank matrices where there is a possibility of overflow, although it comes with the additional computational cost of computing size(mat, 1) extra logarithms.

Note
This generic interface is meant to facilitate simultaneous computation of the Cholesky factorization and determinant of a input positive definite matrix.
If the Cholesky factorization is already computed, simply compute the determinant as the square of the multiplicative trace of the Cholesky factor.
Parameters
[in]mat: The input contiguous matrix of shape (1:ndim, 1:ndim) of
  1. type complex of kind any supported by the processor (e.g., CK, CK32, CK64, or CK128),
  2. type real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128),
containing a subset of the positive-definite matrix whose log(sqrt(determinant)) is to be computed.
[in]subset: The input scalar that can be either,
  1. the constant uppDia implying that the upper-diagonal triangular block of mat should be used for building the lower-diagonal Cholesky factor in the output chol.
  2. the constant lowDia implying that the lower-diagonal triangular block of mat should be used for building the upper-diagonal Cholesky factor in the output chol.
This argument is merely a convenience to differentiate the different procedure functionalities within this generic interface.
[out]detSqrtLog: The output scalar of type real of the same kind as the inputmatrepresenting the natural logarithm of the square root of its determinant.<br> \param[out] info : The output scalarintegerof default kind [IK](@ref pm_kind::IK) that is0<b>if and only if</b> the Cholesky factorization succeeds.<br> Otherwise, it is set to the order of the leading minor of the specified input subset ofmat` that is not positive definite, indicating the occurrence of an error and that the factorization could not be completed.
A non-zero value implies failure of the Cholesky factorization.
A non-zero info implied the input mat is not positive definite.
[in,out]chol: The input/output matrix of the same type, kind, and shape as the input mat containing the Cholesky factorization in its triangular subset dictated by the input arguments subset and operation.
See the documentation of the input argument mat above for more information.
[in]operation: The input scalar that can be either,
  1. the constant nothing implying that the same subset of the output chol as the input subset must be populated with the Cholesky factorization.
  2. the constant transHerm implying that the complex transpose of the computed Cholesky factorization must be written to the output chol.

Warning
The condition size(mat, 1) == size(mat, 2) must hold for the corresponding input arguments.
This condition is verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.
The input mat is assumed to be positive-definite, otherwise the Cholesky Factorization within the procedure will fail, in which case, the procedure will return the control with info /= 0.
The pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds.
