当我在校准数据上运行go_calib_optim时，我得到：
Error using -
Matrix dimensions must agree.
Error in compute_extrinsic_init (line 66)
Y = X_kk - (X_mean*ones(1,Np));
Error in comp_ext_calib (line 22)
[omckk,Tckk] = compute_extrinsic_init(x_kk,X_kk,fc,cc,kc,alpha_c);
Error in go_calib_optim_iter (line 293)
comp_ext_calib;
Error in go_calib_optim (line 56)
go_calib_optim_iter;
Error in calibration_script (line 176)
go_calib_optim;
可能导致这种情况的原因是什么？或者，这个例程是可选的吗？它说它是主要的优化程序，但它有多重要？我可以承受校准数据中的轻微到中等误差。
