DECM
Return the first or second derivative of f( x ) , re-
spectively, with the function f(x) being specified
in a routine starting with LBL label . The return
stack will have y , z , and t cleared and the posi-
tion x in
L
.
Either command will attempt to call a user rou-
tine labeled '
δx' to provide a fixed step size
dx . If
that routine is not defined, a step size of 0.1 is
employed instead.
