I am following the code obtained in matlab file exchange for the paper
He calculates the Hessian matrix as follows using Jacobian Matrix J,
**H = inv(J'*J); % Hessian matrix,**
How is this relation true.
And also the g value used is 1 to construct the COST function to be minimized using LEAST SQUARES , but should'nt it be the local gravity value at the particular place you are carrying out the calibration??
Link to the code :
Please throw some light on this. Thank You.
