The ProdEntries class.
The product of the entries in an expression.

Expression objects, vectors, or matrices. |
axis |
(Optional) The dimension across which to apply the function: |
keepdims |
(Optional) Should dimensions be maintained when applying the atom along an axis? If |
object |
A ProdEntries object. |
values |
A list of numeric values for the arguments |
idx |
An index into the atom. |
value |
A numeric value. |
to_numeric: The product of all the entries.
sign_from_args: Returns the sign (is positive, is negative) of the atom.
is_atom_convex: Is the atom convex?
is_atom_concave: Is the atom concave?
is_atom_log_log_convex: Is the atom log-log convex?
is_atom_log_log_concave: is the atom log-log concave?
is_incr: Is the atom weakly increasing in the argument idx?
is_decr: Is the atom weakly decreasing in the argument idx?
.column_grad: Gives the (sub/super)gradient of the atom w.r.t. each column variable
.grad: Gives the (sub/super)gradient of the atom w.r.t. each variable
exprAn Expression representing a vector or matrix.
axis(Optional) The dimension across which to apply the function: 1 indicates rows, 2 indicates columns, and NA indicates rows and columns. The default is NA.
