Basic maths operations on any combination of any
objects. You can add a slider to a matrix, for example,
then divide by an image. Hopefully most of these are
Arithmetic / Absolute Value Vector
The absolute value item normally calculates mod
of each band of an image separately. By contrast,
Absolute Value Vector treats each pixel as
a vector and calculates the modulus of that.
- These aren’t really maths operations, but they’re
in here too.
