Calculate-Electrolytes Average value

Hey all, I need to do next task:

Write a function which calculates a Electrolytes Average value.
Input data are:
1.sampled signal (vector)
2.sampling rate
3.frequency of first harmonic.
This is my solution, and I am not sure is it good.

My problem is cuz I dont use first harmonic's frequency at all, that's why I am not sure in mine solution

function Yavg=el_avg_val(y,f_s,f_o)
fmax=f_s/2;
max=1/fmax;
%I read that 10 points per max frequency's period is good enough to recognize a signal

delta=max/10;
t=0:delta:max;
N=length(t);
Yavg=sum(abs(y)/N)
end

My second slution:

function Yavg=el_avg_val(y,f_s,f_o)

t=0:1/f_s:1_f_o;
N=length(t);
Yavg=sum(abs(y)/N)
end
