Parabolic function

| Vector | C |
in the palette on the schematic
The block implements the transformation of the input signal (scalar or vector) according to the formula:

where a0, a1, a2 are the coefficients of the parabola, x(t), y(t) are the input and output signals.

Inputs

  • input - the port for the function argument input.

Outputs

  • output - the port of the function value output.

Properties

  • Constant term, in the formula a0+a1·x+a2·x² – the coefficient a0.
  • Coefficient at x – the coefficient a1.
  • Coefficient at x² – the coefficient a2.
Properties can be vectors whose dimensions must be equal to the dimension of the input, in this case, the output will also be a vector.

Parameters

none

Note:
  1. By default, this block implements the quadratic transformation of the input scalar signal with the properties a0=0, a1=0, and 2=1.
  2. Named properties can be set as local model variables (or submodels) in a programming language script, as global project signals using the Tools → Signals main menu item, or as external project signals using an attachable signal database.
