This model generates a voltage by linear
interpolation in a given table. The time points and
voltage values are stored in a matrix table[i,j],
where the first column table[:,1] contains the time points and the
second column contains the voltage to be interpolated. The table
interpolation has the following properties:
- The time points need to be monotonically
increasing.
- Discontinuities are allowed, by providing the
same time point twice in the table.
- Values outside of the table range, are
computed by extrapolation through the last or
first two points of the table.
- If the table has only one row, no
interpolation is performed and the voltage value is just returned
independently of the actual time instant, i.e., this is a constant
voltage source.
- The table is implemented in a numerically sound way by
generating time events at interval boundaries.
This generates continuously differentiable values for the
integrator.
Example:
table = [0 0
1 0
1 1
2 4
3 9
4 16]
If, e.g., time = 1.0, the voltage v = 0.0 (before event), 1.0 (after event)
e.g., time = 1.5, the voltage v = 2.5,
e.g., time = 2.0, the voltage v = 4.0,
e.g., time = 5.0, the voltage v = 23.0 (i.e., extrapolation).
