I need to plot "e" by function of all values of "dm" i but can't do it please help

clc

clear all

F=2000 ;

dm=[12: 5: 37];

f=0.2 ;

l=2 ;

Q= ((F.*dm)/2)*((l+(pi*f.*dm)/((pi.*dm)-(f*l)))) ;

e= (F*l)/(2*pi.*Q);

plot(dm,e)

Answer 1

[Stephan]

F=2000 ;
dm=[12: 5: 37];
f=0.2 ;
l=2 ;
Q= ((F.*dm)/2)*((l+(pi*f.*dm)/((pi.*dm)-(f*l)))) ;
e= (F*l)./(2*pi.*Q);
%       ^
%       |
%       --- elementwise division - "/" is a matrix operator 
plot(dm,e)
