pm_arrayCenter::setCentered Interface Reference

Center the contents of the input array within the output arrayCentered while filling the newly added elements (if any) with the user-specified fill. More...

Detailed Description

Center the contents of the input array within the output arrayCentered while filling the newly added elements (if any) with the user-specified fill.

Additionally, if the left and right margins lmsize, rmsize are specified, center the input array within the section arrayCentered(lmsize + 1 : size(arrayCentered) - rmsize) and optionally fill the margins with the user-specified lmfill and rmfill.

Parameters
[in,out]arrayCentered: The output contiguous array-like object of shape (:) of the same type and kind as the input array, containing the contents of array centered within it, with the requested margins and fillings.
[in,out]array: The input contiguous array of shape (:) of either
  • type character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) of the same length type-parameter as that of array, or
  • type integer of kind any supported by the processor (e.g., IK, IK8, IK16, IK32, or IK64), or
  • type logical of kind any supported by the processor (e.g., LK), or
  • type complex of kind any supported by the processor (e.g., CK, CK32, CK64, or CK128), or
  • type real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128),
or,
  • a scalar character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU),
whose contents will be copied to the center of arrayCentered after subtracting the lmsize and rmsize elements from the left and the right of arrayCentered.
[in]lmsize: The input scalar integer of default kind IK representing the width of the left-margin of the output arrayCentered
(optional, default = 0. It must be present if and only if the input argument rmsize is also present.)
[in]rmsize: The input scalar integer of default kind IK representing the width of the right-margin of the output arrayCentered
(optional, default = 0. It must be present if and only if the input argument lmsize is also present.)
[in]fill: The input scalar of the same type and kind as the input array containing the value to fill the new elements (if any) of arrayCentered surrounding the original array contents (excluding the margins). If array is of type character, then
  1. the equality len(fill) == 1 must also hold if array is a scalar string.
  2. the equality len(fill) == len(array) must also hold if array is an array of strings.
(optional, if missing, the new elements in arrayCentered will remain uninitialized.)
[in]lmfill: The input scalar of the same type and kind as the input array containing the value to fill the left margin (if any) of output arrayCentered. If array is of type character, then
  1. the equality len(lmfill) == 1 must also hold if array is a scalar string.
  2. the equality len(lmfill) == len(array) must also hold if array is an array of strings.
(optional, if missing, the left-margin will remain uninitialized. It can be present only if lmsize and rmsize are also present.)
[in]rmfill: The input scalar of the same type and kind as the input array containing the value to fill the right margin (if any) of output arrayCentered. If array is of type character, then
  1. the equality len(rmfill) == 1 must also hold if array is a scalar string.
  2. the equality len(rmfill) == len(array) must also hold if array is an array of strings.
(optional, if missing, the right-margin will remain uninitialized. It can be present only if lmsize and rmsize are also present)

Definition: pm_arrayCenter.F90:35
Warning
Note that the new elements of the output arrayCentered are not initialized to any particular value if fill is missing.
Therefore, the contents of the new elements of the output array is processor dependent, frequently meaningless and should not be relied upon.
However, if fill is specified, then all new elements will be filled with the specified fill value.
Similarly, the margin elements will not be initialized to any particular values unless the corresponding lmfill or rmfill arguments are present.
When the specified new array size is smaller than the original, the corresponding elements of the old array will be also trimmed from the resized shrunk array (after taking into account the left and the right margins).
In such a case, there will be no new elements to initialize their values and fill will have no effects on the output.
The sum of the input lmsize and rmsize arguments must not be larger than the size of the input arrayCentered.
These conditions are verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.
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.

Test:

Bug:

Status: Unresolved
Source: GNU Fortran Compiler gfortran version 10.3
Description: GNU Fortran Compiler gfortran cannot handle regular allocation for assumed-length allocatable character types and returns the following error.
Fortran runtime error: Integer overflow when calculating the amount of memory to allocate


Remedy (as of ParaMonte Library version 1.5): The preprocessor conditions bypass this bug.

Remedy (as of ParaMonte Library version 2.0.0): The new interface allocatable output arguments entirely, thus obviating the need to handle this gracefully.

Todo:
Normal Priority: Two new optional input scalar lbcold and ubcold arguments can be added to procedures to specify a subset of the contents of the original array that has to be kept in the newly allocated centered array.
