Args

Function: args (<expr>) Returns the list of arguments of expr, which may be any kind of expression other than an atom. Only the arguments of the top-level operator are extracted; subexpressions of expr appear as elements or subexpressions of elements of the list of arguments.

expr: x . dx . dy + z . dy . dz + y . dx . dz;
expr2: x . [dx, dy] + z . [dy, dz] + y . [dx, dz];
expr3: x * [dx, dy] + z * [dy, dz] + y * [dx, dz];
expr4: [x, dx, dy] + [z, dy, dz] + [y, dx, dz];
expr5: [[x, dx, dy], [z, dy, dz], [y, dx, dz]];
expr6: x . del(x) . del(y) + z . del(y) . del(z) + y . del(x) . del(z);
part(expr, 1);
length(expr);
op(expr);
args(expr);
map(op, args(expr));
map(args, args(expr));
map(args, args(expr6));
diffform(vars, expr) := block(    [n, k],    0);
diff(x + y);

The order of the items in the list may depend on the global flag inflag.

args (<expr>) is equivalent to substpart ("[", <expr>, 0). See also substpart, and op.

There are also some inexact matches for args. Try ?? args to see them.
