CSHIFT— Circular shift function
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 scaler of type
INTEGERin 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.
A = CSHIFT(A, SHIFT[,DIM])
|ARRAY||May be any type, not scaler.
|SHIFT||The type shall be |
|DIM||The type shall be |
