Not enough input arguments. Error in ratio_magnitude (line 6) RV1 =1/sqrt(1+((f*s)/p)^2);

function [RV1]= ratio_magnitude(p, s, f)
%This function calculate the ratio of the magnitude of the input voltaje
%   The function has as a imput the ratio and the voltaje also an array
%   with 200 points of w

RV1 =1/sqrt(1+((f*s)/p)^2); 
end

It seems you are not providing inputs to the function and starught away running to code.......you cannot use a function like that. You need to save it, go to the folder where the function is present and define funcitons inputs and then call the function.

p = rand ;  % give your value here instead of rand
s = rand ;   % give your value here instead of rand
f = rand ;  % give your value here instead of rand
RV1= ratio_magnitude(p, s, f)

p=...; values here
s=...;
f=...;
RV1 = ratio_magnitude(p, s, f) % function call

% save function as a separate file named ratio_magnitude.m 
function RV1 = ratio_magnitude(p, s, f)
%This function calculate the ratio of the magnitude of the input voltaje
%   The function has as a imput the ratio and the voltaje also an array
%   with 200 points of w
RV1 =1./sqrt(1+((f.*s)./p).^2);  % use dot infront of arithmetic operators
end
