how to start with 0 (zero) in for loop?

41 views (last 30 days)
for i = 1:n_slice
x(i) = i*deltar;
R(i) = x(i)+rb;
% Evaluate the pressure angle at Ri
theta(i) = acos(rb/R(i));
%Evaluate the involute angle at Ri
inv_ang(i)= tan(theta(i))-theta(i);
% Evaluate the Circular Tooth Thickness at Ri
ctt(i) = (2.*R(i))*((0.5*cptt/rp) + theta_pitch - inv_ang(i));
B = 0.5*(ctt(i)/R(i));
%Eventually, Coordinates might be evaluated
X(i) = R(i)* sin(B);
Y(i) = R(i)* cos(B);
plot(X(i),Y(i),'-r',X(i),Y(i),'+b','LineWidth',2,'MarkerSize',3)
plot(-X(i),Y(i),'-r',-X(i),Y(i),'+b','LineWidth',2,'MarkerSize',3)
end
WHEN I START WITH 0 (ZERO) IT GIVES ERROR. BUT I NEED TO START WITH ZERO NOT 1 !!!

Use
for i = 1:n_slice+1
x(i) = (i-1)*deltar;

but I wonder why matlab does not allow to start from 0? and is there any different way to do it?
