# Matlab homework

problem 1 – Write a function that outputs the vertical deflection of the beam at a point x of interest. Call the function deflection_yourlastname. The function inputs would be: 1) distance from the left end to the point of interest, x 2) length of the beam L 3) load, P 4) location where the load P is applied, a 5) Young’s modulus of the beam, E 6) Moment of inertia, I The output of the function will be the beam deflection, V. Display this output with an fprintf. Run the file for the following input sets: a) x=2.5, L=5, a=3, E=30e6, I = 0.0256, P=30 b) x=4.05, L=5, a=3, E=30e6, I = 0.0256, P=30

Problem 2

Write a function that checks whether a matrix is tridiagonal or not. A tridiagonal matrix is such that has nonzero elements on its main diagonal, the first diagonal below this and the first diagonal above the main. Outside of this, all other elements are zeros.
