Plot does not appear.

for E1=1:73

W=15;

L=1.3;

w=0.25;

h=0.075;

I=(w*h^3)/12;

Deflection5 = (W.*L.^3)/(3.*E1.*I)

plot(E1,Deflection5)

end

Guys why it does not appear what is the problem? I tried to make plot of the E1 values and Deflection while both values changing.

E1=1:73
W=15;
L=1.3;
w=0.25;
h=0.075;
I=(w*h^3)/12;
Deflection5 = (W.*L.^3)./(3.*E1.*I)
plot(E1,Deflection5)

Is it possible to make it with for loop?

[Torsten]

E1 = 1:73;
W=15;
L=1.3;
w=0.25;
h=0.075;
I=(w*h^3)/12;
for i=1:numel(E1)
  Deflection5(i) = (W*L^3)/(3*E1(i)*I)
end
plot(E1,Deflection5)

Thank you! and can you help me for legend command if you know?

[Torsten]

xlabel('E1') 
ylabel('Deflection') 

For other formalities, see

[Ömer Fatih Özdemir]

for example, how to use two plot in legend?

L1=linspace(0.001,1.3);

Deflection1 = (W.*L1.^3)/(3.*E.*I);

plot(L1,Deflection1)

this and

Deflection5

[Torsten]

plot(L1,Deflection1)
hold on
plot(L1,Deflection5)

No need for a for loop

E1=1:73;
W=15;
L=1.3;
w=0.25;
h=0.075;
I=(w*h^3)/12;
Deflection5 = (W.*L.^3)./(3.*E1.*I);
plot(E1,Deflection5)
