file name res.m

load vi.txt
zl=47:16:415;
imp=vi(:1)./vi(:2);
imp=app;
zz=zl*cos(48.0*pi/180);
rr=zl*sin(48.0*pi/180);
res=zeros(11,21)*NaN;
mm=0;

Hi Greg,

I guess that's why he's a supervisor. :)

The v/v line should be

vi(:,1)./vi(:,2)

and appears to be impedance = voltage/current, divided term-by-term. However, the very next line replaces imp with something else.

hi David

yeah you are right i've omitted it,it is vi(:,1)./vi(:,2)
