Error - not enough input arguments, error in qfunc

Hi I'm trying to input an equation to calculate eb/no. the equation to use is:

   P_b = 10^-6
    ebNo=0.5*((qfunc^-1)*(P_b))^2

When I run this script I get the error:

Not enough input arguments.

Error in qfunc (line 17)

if (~isreal(x) || ischar(x))

Error in Comms_Principles (line 22)

ebNo=0.5*((qfunc^-1)*(P_b))^2;

I'd be grateful for any assistnace.

well, you should input a variable for qfunc as you can see here.

You have no argument in your function, that's why you're getting such error.
