Parameters
-
x
-
Specify the start of the range in which to interpolate.
-
y
-
Specify the end of the range in which to interpolate.
-
a
-
Specify the value to use to interpolate between x
and y
.
Description
mix
performs a linear interpolation between
x
and y
using
a
to weight between them. The return
value is computed as $x \times (1 - a) + y \times a$.
The variants of mix
where
a
is genBType
select
which vector each returned component comes from. For a component
of a
that is false, the corresponding
component of x
is returned. For a
component of a
that is true, the
corresponding component of y
is returned.
Components of x
and
y
that are not selected are allowed to be
invalid floating-point values and will have no effect on the
results.
