This is the error I get when I attempt to use quadl:

??? Attempted to access y(13); index out of bounds because
numel(y)=1.

Error in ==> quadl at 78
if ~isfinite(y(13))

This is the section of quadl it sends me to:
% Fudge endpoints to avoid infinities.
if ~isfinite(y(1))
y(1) = feval(f,a+eps(superiorfloat(a,b))*(b-a),varargin{:});
fcnt = fcnt+1;
end
if ~isfinite(y(13))
y(13) = feval(f,b-eps(superiorfloat(a,b))*(b-a),varargin{:});
fcnt = fcnt+1;
end

Commonly, that error indicates that the function you've written and passed
into QUADL does not meet the requirements listed in the documentation:

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/quadl.html

"fun accepts a vector x and returns a vector y, the function fun evaluated
at each element of x."

If you call your function with a vector of values, does it return a vector
the same size and shape? If not, it needs to do so.
