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 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 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.|
Fortran 95 and later
RESULT = EOSHIFT(ARRAY, SHIFT [, BOUNDARY, DIM])
|ARRAY||May be any type, not scalar.|
|SHIFT||The type shall be
|BOUNDARY||Same type as ARRAY.|
|DIM||The type shall be
Returns an array of same type and rank as the ARRAY argument.
