Discrete time simulation
out[i] = in0[i] + in1[i] + in2[i]
The math block adds an arbitrary number of input streams element by element, \
and produces and single output stream. Elements may be single numbers, \
or vectors of numbers, depending upon the value of the vec length parameter.
The preload parameter allows users to implement feedback loops with this math block. \
For example, to enable a feedback of 1 on the 2nd port, set preload to [0, 0, 1]. \
