### Functions/Subroutines

subroutine slamrg (n1, n2, a, strd1, strd2, index)
SLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.

## Function/Subroutine Documentation

### subroutine slamrg (integer n1, integer n2, real, dimension( * ) a, integer strd1, integer strd2, integer, dimension( * ) index)

SLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.

Purpose:

``` SLAMRG will create a permutation list which will merge the elements
of A (which is composed of two independently sorted sets) into a
single set which is sorted in ascending order.```
Parameters

N1

`          N1 is INTEGER`

N2

```          N2 is INTEGER
These arguments contain the respective lengths of the two
sorted lists to be merged.```

A

```          A is REAL array, dimension (N1+N2)
The first N1 elements of A contain a list of numbers which
are sorted in either ascending or descending order.  Likewise
for the final N2 elements.```

STRD1

`          STRD1 is INTEGER`

STRD2

```          STRD2 is INTEGER
These are the strides to be taken through the array A.
Allowable strides are 1 and -1.  They indicate whether a
subset of A is sorted in ascending (STRDx = 1) or descending
(STRDx = -1) order.```

INDEX

```          INDEX is INTEGER array, dimension (N1+N2)
On exit this array will contain a permutation such that
if B( I ) = A( INDEX( I ) ) for I=1,N1+N2, then B will be
sorted in ascending order.```
