5.7 Math
Basic maths operations on any combination of any objects. You can add a slider
to a matrix, for example. Hopefully most of these are obvious.
- 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.
- List
- These aren't really maths operations, but they're in here too.
