Please consider adding some functions used in digital
signal processing, like:

* Heaviside step function
u(x) = 0 if x<0
u(x) = 1 if x>0

* Kronecker delta
delta(x) = 1 if x = 0
delta(x) = 0 otherwise

* rectangular function

* convolution

Thanks.

    I've now implemented heaviside step function, kronecker delta,
    rectangular function, and some related functions (such as triangular
    and ramp functions).

    So far it was very easy. Convolution on the hand is a lot more
    complicated. Maybe it can help if you specify for which purposes and
    functions (or perhaps matrices) you need it.
