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.
