problem with my code in Matlab

Hi,
I have a problem with my code and i need your help.This is my code

A=12.56e-4;
L=0.44;
G=2;
T=300;
q=1.6e-19;
k=8.62e-5;
Edot=0.05;
Ndot=5e9;
DE=0.25;
syms E;
denom=1+exp((E-(v/L))/(k*T));
function1=1./denom;
static=(G*Ndot)/(sqrt((pi*DE)/2));
ek8eths=((E+Edot+(v/L))/DE).^2;
function2=exp(-2*ek8eths);
final=function1.*function2.*static;
inline_final = vectorize (inline (char (final)));
subtotal = quad (inline_final, 0, 1e12);

When i run it with values v=-1,-2 for example then the program gives me a solution,the integral which i want.When i try to run it for a matrix of v 281x1(-12:0.05:2) then i have these errors

??? Error using ==> inlineeval

Error in inline expression ==> array([[67930201350122255859375./549755813888./(772894735361391./1125899906842624+772894735361391./1125899906842624.*exp(50000./1293.*E+200000./431)).*exp(-2.*(10./3.*E-119./3).^2)]....................[67930201350122255859375./549755813888./(772894735361391./1125899906842624+77

On line 34 ==> INLINE_OUT_ = inlineeval(INLINE_INPUTS_, INLINE_OBJ_.inputExpr, INLINE_OBJ_.expr);

Error in ==> C:\MATLAB6p5\toolbox\matlab\funfun\quad.m
On line 59 ==> y = feval(f, x, varargin{:});

Error in ==> C:\MATLAB6p5\work\integral.m

Can anyone knows where is the problem in inline_final and subtotal function?
Thank you
