Please, Borja, format your code properly. Consider that this advice has been given over thousands of times already and that it is in your interest to increase the readability of your question.
Please post the complete error message, most of all the line, which causes the problem.

Wich one is your line four?
function [dados, Vx, Vy] =PLineares(AP,ML,SR)
pi=3.141592653589793238;
z=1.645;
n=length(AP); %%%%IS THIS YOUR LINE FOUR?????
dt=SR/n;
T=dt*n;
%------------------------------------------
APcm=AP*100;
MLcm=ML*100;
dx=diff(abs(APcm));
dy=diff(abs(MLcm));
for i=1:n-1
DOT_(i)=(APcm(i+1)-APcm(i))^2+(MLcm(i+1)-MLcm(i))^2;
end
DOT_AP= norm(APcm);
DOT_ML= norm(MLcm);
DOT = sqrt(DOT_AP^2+DOT_ML^2)
%------------------------------------------
Vap=DOT_AP/T;
Vml=DOT_ML/T;
Vr=DOT/T;
dx=diff(APcm);
dy=diff(MLcm);
%------------------------------------------
Vx=dx./dt;Vy=dy./dt; Vx(n)=Vx(n-1);Vy(n)=Vy(n-1);
%****************************************
ACPap = max(APcm) - min(APcm);
ACPml = max(MLcm) - min(MLcm);
V = cov(APcm,MLcm);
[vec,val] = eig(V);
axes = 2.4478*sqrt(svd(val));
Area = pi*prod(axes);
%--------------------------------------------------------------
dados(1)=DOT;
dados(2)=DOT_AP;
dados(3)=DOT_ML;
dados(4)=ACPap;
dados(5)=ACPml;
dados(6)=Area;
dados(7)=Vr;
dados(8)=Vap;
dados(9)=Vml;
%--------------------------------------------------------------

How did you call this program? Did you define the required input arguments? The correct calling method is typing this into the command window, a script or a function:
[dados, Vx, Vy] = PLineares(AP, ML, SR)

Borja,
you have to give values to AP ML and SR. For example:
[dados, Vx, Vy] = PLineares([1 2 3], [1 2 3], 3)
please notice that your code requires AP and ML to be the same size
