Re: Help graphing SWR

[Jason Martin]

Bah.. sent the original response only to Joe.

So essentially it is because I am dumping the entire formula at once?

You need to create the SWR function to calculate the swr element by element of x.  I'm not quite sure that I got it right, but ... something like this (and I hope that someone will correct my uneducated attempt at this):

function retswr = swr(x)

tt=tan( pi*x/2);
num = 25+j*35.36*tt;
den = 35.36+j*25*tt;
r = abs(num./den);

retswr = (1+r)./(1-r);

endfunction

Then you can do:


x = linspace (-10, 10, 500);
y = swr(x);
plot(x,y)

Søren,


    I changed it to 500, but a still yields a single value.
