Variable amplitude exponential function

| Vector |
in the palette on the schematic
The block returns the output value calculated by the formula:

where a is the multiplier (amplitude or gain), b is the power coefficient, x1(t), x2(t) – the 1st and 2nd input signal of the block.

Mandatory сondition: x1(t)>0.

Inputs

  • x1 - port for the x1 argument;
  • x2 - port for the x2 argument;

Outputs

  • output - the port for the function value.

Properties

  • Multiplier in the function a·x ^[b·x₂] – the coefficient a;
  • Coefficient of the power – the coefficient b.
Properties can be vectors whose dimensions must be equal to the dimension of the inputs, in this case, the output will also be a vector.

Parameters

none

Note:
  1. By default, this block implements an "power" transformation with a variable amplitude of the input scalar signal with the properties a=1, b=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.
