Detailed Description

Sort the input local error estimates list (resulting from the interval subdivision process of the Adaptive Global quadrature procedures of this module) in descending order.

Two error estimates are inserted using the sequential search method at each call to this interface, top-down for the largest error estimate and bottom-up for the smallest error estimate.

Remarks

This generic interface is meant to be primarily by and used within the Adaptive Gauss-Kronrod quadrature routines of the parent module.
There is practically no usage for this generic interface outside of the parent module.

Parameters

[in]	nintmax	: The input scalar of type integer of default kind IK, containing the maximum number of subintervals allowed in the quadrature.
[in]	sinfoErr	: The input vector of size (1:nint <= nintmax), containing the local error estimates from the quadrature subintervals.
[in,out]	sindex	: The input/output contiguous vector of the same type, kind, and size as sinfoErr(:), the first k elements of which contain pointers to the error estimates, such that sinfoErr(sindex(1)), ..., sinfoErr(sindex(k)) form a decreasing sequence, with k = nint if nint <= (nintmax / 2 + 2), and k = nintmax + 1 - nint otherwise.
[in,out]	nrmax	: The input/output scalar of type integer of default kind IK, containing the index of element of sindex(:), such that maxErrLoc = sindex(nrmax) number of calls made to the procedure.
[in,out]	maxErrLoc	: The input/output scalar of type integer of kind IK, containing the nrmax-th largest error estimate currently in the error list.
[out]	maxErrVal	: The output scalar of the same type and kind as sinfoErr(:), containing the nrmax-th largest error estimate in the error list.

Possible calling interfaces ⛓

use pm_quadPack, only: setErrSorted
 
call setErrSorted(nintmax, sinfoErr, sindex, nrmax, maxErrLoc, maxErrVal)

Warning

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.
