cFactor()
Catalog >
cFactor(
Expr1
,
Var
)
returns
Expr1
factored
with respect to variable
Var
.
Expr1
is factored as much as possible
toward factors that are linear in
Var
, with
perhaps non-real constants, even if it
introduces irrational constants or
subexpressions that are irrational in other
variables.
The factors and their terms are sorted with
Var
as the main variable. Similar powers of
Var
are collected in each factor. Include
Var
if factorization is needed with respect
to only that variable and you are willing to
accept irrational expressions in any other
variables to increase factorization with
respect to
Var
. There might be some
incidental factoring with respect to other
variables.
For the Auto setting of the
Auto or
Approximate
mode, including
Var
also
permits approximation with floating-point
coefficients where irrational coefficients
cannot be explicitly expressed concisely in
terms of the built-in functions. Even when
there is only one variable, including
Var
might yield more complete factorization.
