I don't know how to input command function, call the function to generate the graph I want. can you help me fix it

function fv=fgliom(T,y)

p1=0.0068;

p2=0.012;

p3=0.002;

i1=4.7*10^-8;

i2=4.7*10^-5;

i3=4.7*10^-8;

c1=510;

c2=510;

a1=510;

a2=510;

a3=510;

s1=1.8*10^-2;

s2=1.8*10^-3;

s3=1.8*10^-3;

v=2;

j=50;

b=0.2;

u=0;

fq = sign(y(5))/2 + 0.5;

gdot=p1*y(1)*(1-(y(1)/c1))-s1*y(1)*(y(2)+y(3))-(i1*y(1)*y(5))/a1+y(1);

fgdot = sign(-gdot)/2 + 0.5;

fv=zeros(5,1);

fv(1)= p1*y(1)*(1-(y(1)/c1))-s1*y(1)*(y(2)+y(3))-(i1*y(1)*y(5))/a1+y(1);

fv(2)= p2*y(2)*(1-(y(2)+y(3))/c2)-s2*y(1)*y(2)-u*fq*y(1)-(i2*y(1)*y(5))/a2+y(2);

fv(3)= p3*y(3)*(1-(y(2)+y(3))/c2)-s3*y(1)*y(3)+u*fq*y(1);

fv(4)= v*gdot*-(fgdot/c1)*y(4)-(i3*y(4)*y(5))/a3+y(4);

fv(5)= j-b*y(5);

clc;clear all;format long;

[T y]=ode45('ftuber',0 200,[10000 0 0 2000 0 500 140]',10^-7);

figure (1);

plot(T,y(:,1),'.-');

title('Grafik A')

legend('u=50')

xlabel('waktu (hari)');

ylabel('MA(t) (sel)');

this is the function , where i should put the command to call the function? plis edit my script
