Description of all source types.
|
|
Convention: the discrete Heavyside function verifies theta(0) = 1.
|
|
|
|
point: Point source
|
|
-------------------
|
|
* src(x) = delta_x,o
|
|
|
|
* arguments: o
|
|
- o: origin, space-separated integer sequence (e.g. "0 1 1 0")
|
|
|
|
z2Band: Z_2 stochastic source
|
|
-----------------------------
|
|
* src(x) = eta_x * theta(x_0 - ta) * theta(tb - x_0)
|
|
|
|
* arguments: ta tb
|
|
- ta: begin timeslice (integer)
|
|
- tb: end timesilce (integer)
