# MIX

## NAME

mix − linearly interpolate between two values

## DECLARATION

 genType mix(genType x, genType y, genType a); genType mix(genType x, genType y, float a); genDType mix(genDType x, genDType y, genDType a); genDType mix(genDType x, genDType y, double a); genType mix(genType x, genType y, genBType a); genDType mix(genDType x, genDType y, genBType a); genIType mix(genIType x, genIType y, genBType a); genUType mix(genUType x, genUType y, genBType a); genBType mix(genBType x, genBType y, genBType a);

## 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.
