%   Classify Implements classification data samples by already built
%   boosted commitee
%~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
%
%    Result = Classify（Learners Weights Data）
%    ---------------------------------------------------------------------------------
%    Arguments:
%           Learners - cell array of weak learners
%           Weights  - vector of learners weights
%           Data      - Data to be classified. Should be DxN matrix 
%                       where D is the dimensionality of data and N 
%                       is the number of data samples.
%    Return:
%           Result   - vector of real valued commitee outputs for Data. 

function Result = Classify（Learners Weights Data）

Result = zeros（1 size（Data 2））;

for i = 1 : length（Weights）
  lrn_out = calc_output（Learners{i} Data）;
  Result = Result + lrn_out * Weights（i）;
