Matrix problem with my vectors

I am tryin to create a vector 0f angles in incrments of 5 from -5 to 25 I have another vector N with 14 elements I am really lost

"I am tryin to create a vector of angles in incrments of 5 from -5 to 25"

angles = -5 : 5 : 25

Result:

angles =
    -5     0     5    10    15    20    25

Let me know if that doesn't cover your question.

theta = (-5:5:25)';%+
n = numel(theta);
N = [-0.906 1.43 2.78 4.20 5.03 5.28 -2.49 0.889 4.16 7.71 11.0 7.30 12.7]*4.45;
FN_c = N -(3.9*(1-cosd(theta)));
D = FN_c.*sind(theta);
S = 96/(1550);
b = 14.5/(39.4);
AR = b^2/S;
L = FN_c.*cosd(theta);
dp = 1.225;
pz = cat(3,1.6, 4.4)*248.8;
V = sqrt(2*pz/dp);

CL = L/0.5*dp.*V.^2*S;
CL_TH = 2*pi*theta/(1+2/AR);
CD = D./(0.5*V.^2*S);
CD_i = CL.^2/pi*AR;
