%Valores iniciales/inicial values

C= 100;

D= 0.1;

b= 0.15;

m= 0.05;

g= 9.81;

h= 0.001;

yn= 0;

vo=0;

yo=0;

yf=0;

%Procedimiento con metodo de Euler/Eulers meythod

for dt=0:h:(5-h)

vf=C*(h/m)*(D-yf)-(g*h)+(vo*(1-(b*h)/m));

vo=vf

yf=yo+vf*h;

yo=yf

end

%I would want to make a scatter for dt and vo, and another for dt and yo

Espero que esto te sirva :D

C= 100;
D= 0.1;
b= 0.15;
m= 0.05;
g= 9.81;
h= 0.001;
yn= 0;
vo=0;
yo=0;
yf=0;
i = 1;
%Procedimiento con metodo de Euler/Eulers meythod 
for dt=0:h:(5-h)
    vf=C*(h/m)*(D-yf)-(g*h)+(vo*(1-(b*h)/m));
    vo=vf;
    v0(i) = vo; %Almacena en una variable que no se volverá a utilizar despues
    yf=yo+vf*h;
    yo=yf;
    y0(i) = yo; %Almacena en una variable que no se volverá a utilizar despues
    i = i+1;
end
dt = 0:h:(5-h)
scatter(dt,v0,'b'); %scatter dt vs vo
figure
scatter(dt,y0,'r'); %scatter dt vs yo
