% mexReadGrad:  read gradient files into a matrix
%
% Usage:
%   gradMatrix = mexReadGrad(type, number)
%   gradMatrix = mexReadGrad('grad.txt')
%
% INPUT
%   type    :  gradient type or gradient file name (.txt)
%              'elec': gradients from camino based on electrostatic energy.
%              'tess': gradients based on tessellation.
%
%   number  :  if type=='elec', then number means the number of samples.
%              if type=='tess', then number means tessellation order.
%
% OUTPUT
%   grad    :  Nx3 matrix, each row is a point in sphere.
