This second volume reflects Witryna16 mar 2024 · It begins with an initial guess, then modifies the guess by using information in the Jacobian matrix. Since each row in the Jacobian matrix is a gradient of a component function, the Gauss-Newton method is similar to a gradient descent method for a scalar-valued function. It tries to move "downhill" towards a local minimum. powder blue dress casual
