voltage and current propagation
[V1,I1] = vprop(V2,I2,Z0,bl)
voltage and current at point z2
line impedance
phase length in radians = beta*l = 2*pi*l/lambda. For a lossy line bl can also be complex, i.e., bl-j*al
vprop(V2,I2,Z0,bl) can be used to find voltage and current propagation along a transmission line
