SHIF Function
Standard Library function that shifts an array along one of its dimensions.
Usage
result = SHIF(array, dimension, shift_amount)
Input Parameters
array—An array.
dimension—An integer (≥0) designating the shift dimension.
shift_amount—An integer specifying the shift amount.
Returned Value
result—An array of the same dimensions as array. The result is obtained from the input array by a shift of shift_amount elements along dimension dimension. The shift is not cyclic; elements behind the shift are unaltered.
Keywords
y—If set, the shift is cyclic.
