`EOSHIFT`

— End-off shift elements of an array*Description*:`EOSHIFT(ARRAY, SHIFT[,BOUNDARY, DIM])`

performs an end-off shift on elements of`ARRAY`along the dimension of`DIM`. If`DIM`is omitted it is taken to be`1`

.`DIM`is a scaler of type`INTEGER`

in the range of 1 /leq DIM /leq n) where n is the rank of`ARRAY`. If the rank of`ARRAY`is one, then all elements of`ARRAY`are shifted by`SHIFT`places. If rank is greater than one, then all complete rank one sections of`ARRAY`along the given dimension are shifted. Elements shifted out one end of each rank one section are dropped. If`BOUNDARY`is present then the corresponding value of from`BOUNDARY`is copied back in the other end. If`BOUNDARY`is not present then the following are copied in depending on the type of`ARRAY`.*Array Type**Boundary Value*Numeric 0 of the type and kind of `ARRAY`.Logical `.FALSE.`

.Character( `len`)`len`blanks.*Standard*:- F95 and later
*Class*:- Transformational function
*Syntax*:`RESULT = EOSHIFT(ARRAY, SHIFT [, BOUNDARY, DIM])`

*Arguments*:-
`ARRAY`May be any type, not scaler. `SHIFT`The type shall be `INTEGER`

.`BOUNDARY`Same type as `ARRAY`.`DIM`The type shall be `INTEGER`

. *Return value*:- Returns an array of same type and rank as the
`ARRAY`argument. *Example*:-
program test_eoshift integer, dimension(3,3) :: a a = reshape( (/ 1, 2, 3, 4, 5, 6, 7, 8, 9 /), (/ 3, 3 /)) print '(3i3)', a(1,:) print '(3i3)', a(2,:) print '(3i3)', a(3,:) a = EOSHIFT(a, SHIFT=(/1, 2, 1/), BOUNDARY=-5, DIM=2) print * print '(3i3)', a(1,:) print '(3i3)', a(2,:) print '(3i3)', a(3,:) end program test_eoshift
