Where is the mistake ?

there is a mistake i could not understand

*i must draw a graph like that:

x=u=10 11 12 13 ... 100000

y=L(u)*

>> u=10:1:100000;

d=4225;

e=(1.917/(4*pi*(10.^-7)*u)+1.326*10.^7);

L=d/e;

plot(u,L);

??? Error using ==> mldivide

Matrix dimensions must agree.

use ./ instead /:

u=10:1:100000;
d=4225;
e=1.917./(4*pi*(10.^-7)*u)+1.326*10.^7;
