为什么UTME最后结果只有一个值 UTMN有很多值

Latitude=TOTAL_DATA(:,4);
Longitude=TOTAL_DATA(:,3);
UTME=[];
UTMN=[];
a=6378.137; e=0.0818192; k0=0.9996; E0=500; N0=0;
for Zonenum=fix(Longitude/6)+31;
lamda0=(Zonenum-1)*6-180+3; %%%%degree
lamda0=lamda0*pi/180; %%%%radian
phi=Latitude*pi/180; lamda=Longitude*pi/180; %%%%radian

v=1/sqrt(1-e.^2.*(sin(phi)).^2);
A=(lamda-lamda0).*cos(phi);
T=tan(phi).*tan(phi);
C=e^2.*cos(phi).*cos(phi)/(1-e.^2);
s=(1-e^2/4-3*e^4/64-5*e^6/256)*phi-...
    (3*e^2/8+3*e^4/32+45*e^6/1024)*sin(2*phi)+...
    (15*e^4/256+45*e^6/1024)*sin(4*phi)-35*e^6/3072*sin(6*phi);

UTME=E0+k0*a*v*(A+(1-T+C).*A.^3/6+(5-18*T+T.^2).*A.^5/120);
UTMN=N0+k0*a*(s+v*tan(phi).*(A.^2/2+(5-T+9*C+4*C.^2).*A.^4/24+(61-58*T+T.^2).*A.^6/720));
