Method Detail

compute

@Cast(value="bool")
public boolean compute(@ByVal
                                           Mat param,
                                           @ByVal
                                           Mat err,
                                           @ByVal
                                           Mat J)

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()).
