I need help with this matlab problem.
The deflection of a structural beam of constant cross section subjected to a transverse loading is related to the internal bending moment inlb as:
load.
measurements, in the second column. Use three different approaches to compute the second derivative of the data that you will need to compute a corresponding vector of values for :
the last two points.
Use MATLAB's gradient function second order centered difference formula twice on the data. First to compute the first derivative and then again to compute the second derivative.
Use MATLAB's gradient function twice on interpolated data that you generate with a clamped spline with inch increments in Set the derivative of the spline equal to at both ends.
Your function should have the following three column vector outputs in order:
The bending moment values calculated using th order centered finite difference formulas.
The bending moment values calculated using the gradient function on the data.
The bending moment values calculated using the gradient function on the clamped spline interpolation of the data.
Note: The first three test cases check each of the three approaches respectively. Code to call your function
