Undefined function or method 'sparameters' for input arguments of type 'char'

Hi guys!I am new here and i have a problem. I am trying to run 4 different S11 parameters on smith chart and i can't get any result. I used the following code:

gamma=complex(0.95-0.57);
[lineseries,hsm] = smithchart(gamma)

But all i get is a blank smith chart !!!

I would appreciate it if someone could enlighten me !

I wonder if you meant

gamma=complex(0.95,-0.57);

yes i am sorry. i define gamma=complex(0.95, -0.57) and then [lineseries,hsm] = smithchart(gamma) but i only get a blank smith chart.

sparameters appears to be in the RF Toolbox ... do you have this installed? Also, your gamma is only a single value, 0.3800 + 0.0000i

how do i see this ?

Use

ver

to determine whether you have the RF Toolbox installed. Use

which -all sparameters

to determine if the code might be installed but not licensed.
