% Designs an L-type matching circuit
Goes between a load and a source so that the source sees effective
resistance r0. r0 must be real. The load has some resistance and reactance.
The output is in units of reactance, but this can be converted into
capacitance or impedance via xC = -1/C*w and xL = L*w.
Type MatchingCircuit for a demo of a 50 ohm purely resistive load.

Form:
[xS,xP,sFirst] = MatchingCircuit( r0, rL, xL, pm )
--------------------------------------------------------------------------
------
Inputs
------
r0 (1,1) Desired effective resistance (Ohm)
rL (1,:) Load resistance (Ohm)
xL (1,:) Load reactance (Ohm), zL = rL + i*xL
pm (1,1) Plus or minus 1, selecting root of solution. Useful for
deciding whether you want to have an inductor in parallel.
-------
Outputs
-------
xS (1,:) Reactance of series element (Ohm).
xP (1,:) Reactance of parallel element (Ohm).
sFirst (1,:) Logical. If true, series element must be first in the
L-type matching network (r0
