CSHIFT— Circular shift elements of an array
CSHIFT(ARRAY, SHIFT [, DIM]) performs a circular shift on elements of
ARRAY along the dimension of DIM. If DIM is omitted it is
taken to be
1. DIM is a scalar 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 shifted back in the other end.
Fortran 90 and later
RESULT = CSHIFT(ARRAY, SHIFT [, DIM])
|ARRAY||Shall be an array of any type.|
|SHIFT||The type shall be |
|DIM||The type shall be |
Returns an array of same type and rank as the ARRAY argument.
