reverse(x), x a vector or matrix. |

reverse(x) reverses the order of the rows of x, where x is a REAL, LOGICAL or CHARACTER vector or matrix. The result has the same size and type as x. When isvector(x) is True, the result is a pure vector (ndims(x) = 1). Otherwise, the result has 2 dimensions. Examples: Cmd> reverse(vector(1,3,2,4,7)) (1) 7 4 2 3 1 Cmd> reverse(matrix(run(6),3)) (1,1) 3 6 (2,1) 2 5 (3,1) 1 4 Cmd> reverse(matrix(vector("A","B","C","D"))) (1) "D" (2) "C" (3) "B" (4) "A"
