prev(X)

X is a vector/matrix/table.

Shift the elements of a vector to the right for one position. In comparison, next shifts the elements of a vector to the left for one position; move shifts the elements of a vector for multiple positions.

x=3 9 5 1 4;
prev(x);
// output: [,3,9,5,1]

x = matrix(1 2 3 4 5);
prev(x)#0

t=table(1 2 3 as a, `x`y`z as b, 10.8 7.6 3.5 as c);
prev(t)
