compute()

virtual bool cv::LMSolver::Callback::compute ( InputArray  param, OutputArray  err, OutputArray  J  ) const

pure virtual

computes error and Jacobian for the specified vector of parameters

Parameters

param	the current vector of parameters
err	output vector of errors: err_i = actual_f_i - ideal_f_i
J	output Jacobian: J_ij = d(err_i)/d(param_j)

when J=noArray(), it means that it does not need to be computed. Dimensionality of error vector and param vector can be different. The callback should explicitly allocate (with "create" method) each output array (unless it's noArray()).
