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.
