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.
