Rotate a 3d mesh model in matlab

I want to rotate and align a 3d mesh model represented in face-vertex form. Transformation of a 3d matrix would have worked if my model was a in point cloud form. I couldn't find a function to convert a face-vertex information to [x y z] point cloud information.

view(-[0 20]);

the above command help to see the image in desired angle but it is not changing the face-vertex values. My 3d object is in .stl format and i used ftread.m function to load it to matlab .

Function to read .stl file

function [fout, vout, cout] = ftread(filename)
% Reads CAD STL ASCII files, which most CAD programs can export.
% Used to create Matlab patches of CAD 3D data.
% Returns a vertex list and face list, for Matlab patch command.
% 
% filename = 'hook.stl';  % Example file.
%
fid=fopen(filename, 'r'); %Open the file, assumes STL ASCII format.
if fid == -1 
    error('File could not be opened, check name or path.')
end
%
% Render files take the form:
%   
%solid BLOCK
%  color 1.000 1.000 1.000
%  facet
%      normal 0.000000e+00 0.000000e+00 -1.000000e+00
%      normal 0.000000e+00 0.000000e+00 -1.000000e+00
%      normal 0.000000e+00 0.000000e+00 -1.000000e+00
%    outer loop
%      vertex 5.000000e-01 -5.000000e-01 -5.000000e-01
%      vertex -5.000000e-01 -5.000000e-01 -5.000000e-01
%      vertex -5.000000e-01 5.000000e-01 -5.000000e-01
%    endloop
% endfacet
%
% The first line is object name, then comes multiple facet and vertex lines.
% A color specifier is next, followed by those faces of that color, until
% next color line.

CAD_object_name = sscanf(fgetl(fid), '%*s %s');  %CAD object name, if needed.
