This information is part of the Modelica Standard Library maintained by the Modelica Association.
This block generates an output signal by linear interpolation in a table. The time points and function 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 data to be interpolated. The table interpolation has the following properties:
Example:
table = [0, 0; 1, 0; 1, 1; 2, 4; 3, 9; 4, 16]; If, e.g., time = 1.0, the output y = 0.0 (before event), 1.0 (after event) e.g., time = 1.5, the output y = 2.5, e.g., time = 2.0, the output y = 4.0, e.g., time = 5.0, the output y = 23.0 (i.e., extrapolation).
